Description of problem: When attempting to run gthumb from a remote host using SSH tunnel, it segfaults. Version-Release number of selected component (if applicable): gthumb-3.2.2-1.fc19.x86_64 How reproducible: 100 % Steps to Reproduce: 1. ssh -X fedora19host 2. cd .../directory_with_images 3. fedora19host$ gthumb . Actual results: libGL error: failed to load driver: r600 libGL error: Try again with LIBGL_DEBUG=verbose for more details. Segmentation fault Expected results: gthumb window displayed at ssh client. Additional info: fedora19host$ LIBGL_DEBUG=verbose gthumb . libGL: OpenDriver: trying /usr/lib64/dri/tls/r600_dri.so libGL: OpenDriver: trying /usr/lib64/dri/r600_dri.so libGL error: failed to authenticate magic 30 libGL error: failed to load driver: r600 libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so Segmentation fault
The same occurs when trying to run it as a different user. Under X runing from a terminal: su <USER> gthumb However, it appears to be related to the dri device permission, error message: libGL error: failed to open drm device: Permission denied Now, /dev/dri/card0 have permission 0660 and group ownership 'video'. If I add the "different user" to the video group then gthumb works. I hope this helps.

Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
