Library monitoring not working, rescan shows nonexistent files and folders, no more "missing files"

Using Ubuntu 11.10 (32 bit), and using Rhythmbox 2.90.1, I set my preferences to watch for changes in the library folder.

Then I make changes within a given subfolder and/or to the subfolder itself, for example, renaming via Nautilus, Soundconverter, or Cowbell, or a combination thereof.

The next time I launch Rhythmbox, it shows nonexistent files in the library. For example, where there is only one file, there are two other copies still shown; one copy is the way the file/folder/both was previously named, and the other copy is in a non-existent folder way outside of the library, with a peculiar name, "/home/dg/(null)/filename" (if the "null" folder exists, I cannot locate it).

In the attached screenshot, the file circled in red is the only file actually present.

This did not happen to me in previous versions of Rhythmbox, at least, not that I am aware of. I'm not sure it was even occurring during the week or two I had done a dist-upgrade from the ~64 bit~ version of Natty to the Oneiric RC (and thus the GTK+3 version of Rhythmbox) before doing a clean install of the 32 bit version of the Oneiric final release.

Unticking and reticking the watch for changes in library option combined with restarting Rhythmbox and rebooting the computer has no effect.

Manually right-clicking on a file in the library view in Rhythmbox, and selecting "move to trash" has no effect other than to place a red error icon on the row of the file in question. Only selecting "remove" in the right-click context menu actually removes it.

*********

This time around, after the fresh install of Ubuntu 11.10, and installing Rhythmbox, and uninstalling Banshee, the only thing I did before setting my library folder was to manually copy and paste some iradio entries into the ~/.local/share/rhythmbox/rhythmbox.db xml database file before it got cluttered with thousands of non-iradio entries (songs).

The "missing files" function in the library UI was briefly working today, as was the "import errors" function, now no files show up as missing, even though they are actually missing. I don't know what changed to cause the different behavior.

*********

Oddly, this bug seems like it may have cured a separate, longstanding bug I've had with Rhythmbox: usually when I restarted Rhythmbox in the past, a restart took two attempts, the first attempt resulting in a crash and the second attempt actually restarting Rhythmbox. So far this does not seem to be happening, but if it resumes I will note it here.

Thank you for taking the time to report this bug and helping to make Ubuntu better, however the report is missing some information, may you please run rhythmbox as: rhythmbox --debug &> rhythmbox-debug.txt ; perform the steps to reproduce the bug and attach that resulting log file to the report? Thanks in advance!.

This is what I did to try to break rhythmbox again:

--------------------------------------------------------------------------------

while rhythmbox is open, in Nautilus I made a temporary music library folder with just one song (as opposed to 30,000 songs, which seems to make the debug output files massively long)

changed the library folder in rhythmbox settings and closed rhythmbox

renamed the ~/.local/shared/rhythmbox/rhythmboxdb.xml file to a backup copy, to start from scratch

opened rhythmbox (output file 01 started)

in nautilus, renamed the song file (the only song in the library); rhythmbox seems to update the file properties correctly

in nautilus created album folder and dragged file in the new subfolder; in rhythmbox, one file still shows, but in the properties dialog, the location is now /home/dg/Desktop/(null)

opened the file in cowbell, changed tag info, saved the changes (which also renames the file itself); still no "missing file" status showing in the rhythmbox sidebar, still only one file showing up, location still /home/dg/Desktop/(null)

opened file with soundconverter, to convert from 192 bitrate to 128 bitrate; this creates a new file in a subfolder; no updating in rhythmbox yet, so went to menu bar to open preferences (which historically has appeared to force a rescan of the library); that did nothing, so i unticked and attempted to retick "watch library for new files" and rhythmbox crashed (in the terminal, the message was "segmentation fault")

restarting rhythbox (output file 02 started)

same erroneous file (just one though) shows in library window, try to play it, but it will not play

in the settings, the "watch library for new files" box did not get ticked before the segfault, so reticking it now; library does not update in rhythmbox

closing rhythmbox via window title bar button; does not stop rhythmbox though (does not terminate in the terminal)

open system monitor and rhythmbox is listed as sleeping with channel being futex_wait_queue_me; selecting end process

restarting rhythmbox (output file 03 started)

now the library shows 3 files, 2 of which exist

in nautilus, deleting the original 192 bitrate file, dragging the new 128 bitrate file up from the subfolder, and deleting the subfolder; the rhythmbox library does drop one file, but still shows the nonexistent file at /home/dg/Desktop/(null); the rhythmbox side pane does update to show a missing file, which i right click and remove

in nautilus I rename the file; rhythmbox updates it correctly

in nautilus, I make a new folder and drag the file into it, and delete the old folder; the one correct file now shows up in the rhythmbox library at /home/dg/Desktop/(null)

restarting rhythbox (output file 04 started)

I try playing the "null" files and then the GUI seems to go into an endless loop; i click the window title bar button to close rhythmbox, and then a third file shows up and the loop stops

i try to play the newly displayed file and the rhythmbox window dims and seems frozen

I clicked the x in the window title bar and selected "force quit"

restarted rhythmbox (output file 05 begun)

the correct file does now play, the two "null" files are st...

What else should I do to make this report "complete"?

[Launchpad Janitor (janitor)]

[Expired for rhythmbox (Ubuntu) because there has been no activity for 60 days.]

[anthropornis (anthropornis)]

I'm trying to bump this bug since it expired.

I've done what was requested of me and am willing to do more, but no one seems to respond.

I've also noticed this seems to be a pattern with Rhythmbox bugs in particular. This seems odd since Banshee is now no longer the default player.

Does Ubuntu prefer that Rhythmbox bugs be posted on a different tracker rather than Launchpad?

If no one is going to respond to bug reports on Rhythmbox, then I will stick with using Guayadeque for music library management.

This looks like a duplicate. Unset it if I'm wrong about this.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Bump! Ubuntu 13.04. Rhythmbox 2.98
