I am not sure if some .lock file remained somewhere or it happened after yesterday's system update, but I cannot start gThumb any more.

When I open it it freezes, turns grey and I have to kill it.

Tried uninstalling it (remove and purge), deleting all gthumb folders with settings, installing new version... nothing helped.

Anyone has ideas how can I reset gThumb and make it work?

  • Which settings folders specifically have you tried deleting? Also, how are you opening gThumb?

  • I tried opening in by double-click on an image (default app), but also tried via console. The same freeze. I deleted settings from /home, but only after I got these issues. The deletion did not cause the issue. I deleted 2 folders gthumb from ~/.config/gthumb and ~/.local/share/gthumb

A tip on http://ask.systutorials.com/715/gthumb-hangs-at-startup-on-fedora helped me: Unmount all iphone mountpoints.

    I had a webdav mount opened. Gthumb unfroze once I have unmounted it. Seams that it has problem with remote mounted directories. This occurred with Ubuntu 19.04. Sep 27 '19 at 11:53
  • i can confirm gThumb has problems with offline mount points. i had several Samba shares mounted, and after the remote device got offline i could not open (local) pictures with gThumb. after unmounting all Shares, everything was fine again. Guess this is distribution agnostic, i am using Manjaro Linux..
