--- Comment #4 from rol...@rptd.ch --- 1) MLT >= 6.0 is masked "testing" in GenToo which is usually for a reason. But Kubuntu has 6.0.0-2 and there it segfaults too so that should not be the reason. 3) Unfortunatly I can't. When I run it with GDB and it crashed KCrash steals the process from GDB and I end up with no stack trace. I see though some strange entries in the GDB before it crashes: QXcbConnection: XCB error: 8 (BadMatch), sequence: 30604, resource id: 67109068, major code: 131 (Unknown), minor code: 3 QXcbConnection: XCB error: 8 (BadMatch), sequence: 30620, resource id: 67109068, major code: 131 (Unknown), minor code: 3 QXcbConnection: XCB error: 8 (BadMatch), sequence: 30637, resource id: 67109068, major code: 131 (Unknown), minor code: 3 QXcbConnection: XCB error: 8 (BadMatch), sequence: 30656, resource id: 67109068, major code: 131 (Unknown), minor code: 3 ( a lot of these actually) and some of these: Attempting to create QWindow-based QOffscreenSurface outside the gui thread. Expect failures. or this one: Overwriting existing old cached entry due to collision. Overwriting existing old cached entry due to collision.
