Hey all,
Somehow kbuildsycoca5 is crashing here lately. I nuked my whole kde
prefix (/usr/local) and rebuilt with packaged qt from my distro
(arch). But kbuildsycoca5 is crashing every time I run it with some
issue in QByteArray. Has anyone seen this lately/before or know how I
can get past it? One of my config files broken or something? (I miss
the days of ~/.kde where I could move that out of the way to figure
out issues like this...) Here's a backtrace of the crash. Currently
running in a gnome terminal in a gnome session to test and such while
the rest of kde builds...
