file-roller hangs a while when extracting item via drag and drop

[Sandro Mani]

Symptom: when dragging a folder from file-roller to the desktop or another folder, file-roller hangs for some time (ca 2-3 minutes) eating all the CPU, then proceeds as expected.
Steps to reproduce: test with OpenFOAM-1.5.General.gtgz from http://www.opencfd.co.uk/openfoam/linux64.html#linux64 (rename gtgz to tgz...)

Issue both on intrepid x86 and x64.

Attaching valgrind profiling data. Note: I interrupted the execution of the program after about 30 minutes...

Thanks for your bug report. Please try to obtain a backtrace of the hang http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

Backtraced attached. I interrupted the program with ctrl+c after about one minute, as otherwise the program would eventually recover from the hangup and finish as expected, this providing no backtrace information.

the stacktrace has no clear indication of a crash, it could just be taking a while to do the work, to send to bugzilla.gnome.org by somebody having the issue

Indeed it is not a crash, but a hang - after a few minutes (this on a 2.66GHz T9550). Looking a bit closer at the archive, the main issue seems that it contains a huge amount of files (i.e. 32'000 files in one folder). But what is strange is that the issue does NOT occur when directly selecting extract here from the context menu... I guess the profiling data best describes the hang.

the bug seems to have enough information to be sent to bugzilla.gnome.org where the people writting the code will read it

I have not observed File Roller coming back to life, but perhaps I am just impatient. Most recent (reproducible) incident...

I downloaded this archive: http://downloads.mozdev.org/flashblock/flashblock-1.5.7.1.xpi
Found flashblock.jar in the archive and dragged / dropped it into Nautilus. This file is about 80 kb. File roller hanged and would not close. It was eventually forced to exit, which I assumed did the trick.

Hours later, my system is firing its fans off continually. Curious (especially given that CPU was running at the minimum 36% frequency), I opened System Monitor. By this time, file-roller was consuming 1.1 GB of memory and was still labelled as a regular sleeping process. mv was listed as a child process; its status was Zombie.
Sorry, I killed the thing in a hurry so didn't collect any more detail, but the failure should be easily recreated. This was generated with a small, uncomplicated archive extracting a single file. I have experienced it with every archive I have used so far.
Like the reporter, I do not have a problem extracting the file through the application's menus; only through dnd.

This did NOT happen with File Roller in Intrepid.

(For the time being, a nice workaround is to use the archive mounter).

Works now.
