Bug Description

i'm getting this segfault

Debug [AnalyserQueue 1]: Beat Calculation complete
Debug [AnalyserQueue 1]: New BeatGrid
Debug [AnalyserQueue 1]: AnalysisDAO fetched 0 analyses, 0 bytes for track 42 in 0 ms
fidlib error: Frequency of -nanHz out of range with sampling rate of 0Hz
Segmentation fault (core dumped)

the tracks in question all show a length of "0" in the browser but if i load them manualy they work fine, and then the library shows the length correctly after loading.

this is on ubuntu precice (standard kernel) with todays trunk.

correction, this happens to all the tracks in the library that have a length of zero but sometimes it only segfaults afer a few secconds.

Can you grab a backtrace after Mixxx crashes?

o.k so i made a backtrace from todays bzr, not that i couldn't imediatly replicate the crash with the same files as yesterday, it seems that mixxx somehow fixed there metadata, but manualy loading annother file that was showing lenght:0 triggered it.
