PCManFM window closes under certain conditions

[djohnston]

This began happening after using newer kernels than 2.6.38.8. Current kernel in use is 3.2.15-pclos1.pae. But I don't think the kernel has anything to do with it. The culprit seems to be libgtk-x11. No errors show in ~/.xsession-errors. Dmesg does show errors.

I reinstalled pcmanfm, libfm, libfm and libgtk+-x11 packages, but the problem persists.

It happens usually after unmounting a removable device in the PCManFM window. After the removable device has been unmounted, I click my home directory icon in the left pane, which results in my home directory contents being shown in the right pane. Everything is fine until I physically remove the removable device, (usually a USB thumb drive). At that point, the PCManFM window disappears from the screen.

It sometimes happens when copying files from one directory or partition to another. The PCManFM window will disappear, causing the file copy process to abort. I can reopen the file manager window and restart the copying without loss of data.

I'm wondering if I should try removing the libgtk-x11-2.0.so.0.2400.4 file itself before reinstalling the libgtk-x11 package. Doing a net search for "error 4 in libgtk" brings up quite a few hits relating to other applications.

It happens usually after unmounting a removable device in the PCManFM window.

I have done a bit of investigation in that area, my results were a bit different:

when I tried the crash/segfault/pcmanfm termination happened only upon the following condition:

a) you open pcmanfm, you mount a device
b) you close that instance of pcmanfm
c) you reopen pcmanfm and while unmounting the device it crashes.

instead, if you work using always the same instance of pcmanfm, (never close it), you can mount and unmount devices how many times you like without any crash.

Could you replicate the same ?

Aha! You are right, I do open and close the window before unmounting. I'll test the same without ever closing PCManFM and see what happens. However, I'm more concerned about the libgtk-x11 segfaults. Think I ought to remove the .so before reinstalling libgtk-x11 again?

Hi,

The Lxde development team is aware of the situation for pcmanfm/libfm, which at this stage crashes as well in other distributions, under various conditions (for some it crashes when changing icons on the desktop) and is working actively to produce a new version. The next should be PCManFM 1.0.

A newer version of Lxpanel : Lxpanel2 is also on it's way.

Thanks, Mel. I ended up renaming libgtk-x11-2.0.so.0.2400.4. Bad move.    Couldn't open any windows.    Had to open a virtual console, login as root, and mv the file back to its original name. While in the virtual console, I thought about just reinstalling the libgtk+-x11-2.0_0-2.24.5-3pclos2011 package. Then I thought, "No, I'll just get into more hot water. I can live with the little quirks."
