I'm trying to find out the reason for a user's Tumbleweed DVDStyler SIGSEGV at :
(gdb) run
Starting program: /usr/bin/dvdstyler

Using host libthread_db library "/lib64/libthread_db.so.1".

The user has tried on three different Tumbleweed installations, one of
which was a clean install. The only library which is different to Leap
is libxcb and xcb-proto which were updated a month ago. I'm unable to
install Tumbleweed and DVDStyler works on my Leap installation. libxcb
has api changes, mostly types but according to abi-compliance-checker
is abi compatible, I previously checked this looking for the reason
for the xine-lib Tumbleweed build failure.
