#8421: mythbackend from trunk rev 24416 crashes while scanning video directory in
libQtCore.so.4
------------------------------------------+---------------------------------
Reporter: dj_maarten@… | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - General | Version: Trunk Head
Severity: high | Mlocked: 0
------------------------------------------+---------------------------------
Recently updated my mythtv version from trunk. When I startup mythbackend
it crashes after 5 seconds. The last line in mythbackend log file shows
UPnpMedia: BuildMediaMap VIDEO scan starting in :/home/mythtv/video
When I use gdb (debugger) this is the output from startup. It seems to
crash in libqtcore.so.4
