#517 PCManFM 0.9.10 crashes when unmounting a peripheral


Since pcmanfm 0.9.10 has been packaged, along with libfm 0.1.17, it is not possible anymore to unmount an internal partition or a USB stick without having the file manager crashing.

In ~/.xsession-errors I get this kind of message:

** (pcmanfm:10980): DEBUG: FmJob error: No such file or directory
** (pcmanfm:10980): DEBUG: try automount
** (pcmanfm:10980): DEBUG: on_mount_action_finished

** (pcmanfm:10980): DEBUG: try automount
** (pcmanfm:10980): DEBUG: on_mount_action_finished

I think there is no debug enabled at compile time, when I run it from console it just gives back the prompt. If I run it in gdb, here is what I get:

Program exited normally.


This happens when I unmount from a subdirectory of the mounted partition and also when the directory used as mount point is in use. I notice that it does not crash if I first go back to an upper directory which is above the directory used as mount point (here /media).

When I revert to a former version, a 0.9.9 with libfm 0.1.15 it does not crash on umount, whatever subfolder is in use.

Thanks if you can fix it in next versions.

    What you've described isn't a crash but normal window closing after unmounting the volume. Cannot remember when it was introduced, possibly in 0.9.10, so AFAIK it's not a bug but feature and there is nothing to be fixed.

    Indeed. This looks more like a normal program exit rather than crash.
    Currently when a directory is being unmount, pcmanfm closes its window.
