bt-full.txt

I can confirm lots of KDE apps and even QT only crash after upgrading to mesa
18.0.0-rc2. This is a stacktrace from qupzilla, a qt browser. Attached is the
same stacktrace but generated with `bt full` so it also shows local variables.

Core was generated by `/usr/bin/qupzilla -session
10ddca7665000151644676500000008200015_1516586983_963'.
