Tragegraph is crashing when opening specific sqlite files:

Unfortunately the trace is too big to upload it (250MB), if you can't reproduce it I'll try to find a trace < 10MB or another way to reproduce.

The attached archive contains a database (I can't upload the database itself) of a trace generated by TracerPIN when attaching to a Java process with an address filter enabled. Tracegraph crashes on my machine when loading this trace. database.zip

second one provokes the crash because it doesn't contain any instructions. I'm not sure it's related to the initial problem. Anyway tracegraph should be more robust on parsing sqlite (or whatever file we throw at it).

Sorry for fixing this so late even though it was an easy fix. But the fix is in commit ad596fe66babbb9f296348b3f42263d3630c52a9 ;-)
