Description of problem: In rawhide gnome-photos which uses gegl deadlocks here on startup while loading up gegl which in turn loads up OpenCL. Please consider disabling opencl support in gegl until the underlying ocl-icd issue is resolved or the dynamic loader in glibc becomes more forgiving of such arrangements. For more information ocl-icd issue https://bugzilla.redhat.com/show_bug.cgi?id=1219646 vlc issue https://bugzilla.redhat.com/show_bug.cgi?id=1205880 gnome-photos-3.16.2-1.fc23.x86_64 gegl03-0.3.0-0.4.gitc9bbc81.fc23.x86_64 ocl-icd-2.2.3-1.git20141005.7cd0c2f.fc22.x86_64
One way to avoid the deadlock of course is to uninstall ocl-icd, which isn't a hard requirement for gegl03
My understanding from bug 1219646 is that ocl-icd is fixed, but there could be some issue in mesa itself. Out of curiosity, which OpenCL implementation is this? eg., the free Intel graphics stack doesn't support OpenCL, but nouveau and radeon does as far as I know. It might be relevant.
Its a glibc issue (not yet fixed in my understanding) and is tracked in bug 1223055

This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle. Changing version to '23'. (As we did not run this process for some time, it could affect also pre-Fedora 23 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora23
So as the glibc report says this should be fixed now in rawhide and f23.. hanve't had a chance to test yet.
