I've had some problems with audio sync and stuttering tv playback the last
few days so i thought i would try the latest master.
But since i was running a pretty old Ubuntu i found it tedious to try to
install Qt5, so i decided to upgrade my Ubuntu to 14.04 LTS, was running
12.04 LTS before.
I know that i would get in some trouble to get everything running again,
but this frontend segmentation fault was a surprise. Don't have a clue how
to find the problem. I know it is master so maybe it is not in a working
condition? (but it usually is) Or there is some other thing that got left
out during the upgrade that makes the frontend crash.
So how could i find out why i get a segmentation fault from the frontend?
What debug level should i use so you guys would be able to help me?
I do see in the backend log that the frontend connects.
Without any extra debug level this is what i get:
