Filesystem browser stops listing files with GtkWarning

[Michael Macnair]

Binary package hint: quodlibet

I can't reproduce this reliably, however it usually happens after browsing for a little while.

The bug is manifest like this: select a folder that contains music files, it displays the files. Select another folder that also contains music, and it doesn't display them - once this has happened it doesn't matter what folder you select (including the previous working folder) - no files will be displayed again until you switch out and back in to the filesystem view. Everything else continues to work: switching to another view and playing files from there; the currently playing song continues to play; the gui is responsive, etc etc.

The error that is spat out when it first fails to list the contents of the folder is:
/usr/share/quodlibet/browsers/filesystem.py:148: GtkWarning: gtk_tree_selection_get_selected_rows: assertion `GTK_IS_TREE_SELECTION (selection)' failed
  model, rows = selection.get_selected_rows()

If you want me to run QL in any kind of debug mode until the bug reappears, I can do so.

SOLUTION:
https://www.sacredchao.net/quodlibet/changeset/4189 is confirmed to be the fix to this issue. It has existed for some time, but there hasn't yet been a ql release to incorporate this fix.

I can confirm this with quodlibet 1.0-1ubuntu1 (gutsy).

[Dana Goyette (danagoyette)]

I can also confirm this; it's rather irritating. Oddly enough, it seemed to work for a while after I had initially installed quodlibet, but then broke once I added stuff to the actual "collection" -- which I don't use, anyway.

[Dana Goyette (danagoyette)]

Marking as confirmed, because three confirmations seems like enough to me.

Dear,

The solution to solve this bug is describe here > > https://www.sacredchao.net/quodlibet/changeset/4189

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? A solution was posted earlier; it would be useful to see if this has made its way into the latest release. Can you try with Ubuntu Hardy Heron or Intrepid Ibex? Thanks in advance.

[bnj (b2besses)]

I can confirm that this bug is still present in ubuntu hardy heron.
I have been able to suppress it by changing filesystem.py as describe in the link above.

[Dana Goyette (danagoyette)]

Intrepid still has this bug, since the filesystem.py file is still as it was before that changeset 4189. I can also confirm that applying those changes to filesystem.py fixes the issue.

[Hew (hew)]

Marking as triaged, as the fix exists, but just hasn't been included in an upstream release yet.

[Dana Goyette (danagoyette)]

Hmm, after applying the fix, QuodLibet no longer maintains folder selection after quitting and re-launching the application -- instead, the application always launches with NO folder selected, and thus with an empty playlist.

[Dana Goyette (danagoyette)]

New observation: After undoing the patch (by purging and reinstalling QuodLibet), I've realized that that behavior (not restoring selected folders) is not an issue with that patch -- the behavior also exists with the original packaged version. If I edit the config file to unset the collection root (normally ~/Music), QuodLibet will again remember last selected folders.

[Trent McPheron (tiz-ex1)]

Does anyone here have a copy of filesystem.py with the applied changes? The sacredchao tracker is gone, and QL's IRC channel hasn't been any help in resolving this.

[bnj (b2besses)]

Here the modified file

[Trent McPheron (tiz-ex1)]

It works like a charm. Thanks a million! :D
