Hello Ozan,
libcogl is part of the cogl package:
$ locate libcogl
/usr/lib64/libcogl-pango.so.0
/usr/lib64/libcogl-pango.so.0.0.0
/usr/lib64/libcogl.so.11
/usr/lib64/libcogl.so.11.0.3
$ rpm -qf /usr/lib64/libcogl.so.11.0.3
cogl-1.12.2-1.fc18.x86_64
I think the problem is not related to cogl as there isn't an update
for it in the repository for a while. The segfault seem to be a
side-effect of another issue since a user reported that the issue is
fixed by reinstalling shared-mime-info.
I'll look into this and further report.
