I recently got the apparently same hang in Kate twice in one day. The
application froze while IIRC not using CPU cycles and didn't recover. I
did not attach gdb. To the best of my knowledge, everything from qtbase
up (5.5 branch) is self compiled so there is no mixing with distro
I have checked "info shared" in gdb and found nothing Qt related coming
from /usr. This is now a few days after the hangs so there is a small
probability that something changed.
