First, it only happens with Unac. Second, it does not happen if I build tracker with "-O0".Well you can probably imagine that I too, like you did as you apparently looked at that variable too, why parser suddenly turns into NULL for you. Perhaps try to nonetheless reproduce with -O0 because as far as I can see is that parser=0x0 a GDB quirk. Perhaps set a break point on 445 and test 'parser' with gdb, then step into 447 and see what happens with it?
Well I do not see anything relevant (Tracker is built with -O0):

Valgrind is also not being very helpful, claiming that it might be a stackoverflow. But then I'm sure it wouldn't consistently happen at the same location. Perhaps also try with another version of libunac?
When I reported the first crash I was using unac 1.7. I also have crashes with unac 1.5. I cannot build unac 1.4 because I use a 64 bits platform. To be honest, I will not be able to dig into unac code because it is too complicated for the time I have. Laurent.
You will find in attachments a valgrind log, a GDB backtrace and the build log of Tracker where I see many warnings that seem to be quite easy to fix. Perhaps I see some of them because I use a 64 bits platform. For each trace, I used the following environment variables : export G_SLICE=always-malloc export G_DEBUG=gc-friendly For each trace, I first launched tracker-store, then tracker-miner-fs. Tracker has been built with default cflags. Just a question about Unac: it seems to be unmaintained and I have been unable to build it directly without hacking parts of its test suite. So is this library a good choice for Tracker? Moreover I would add that it is not shipped with Fedora 11 and I am not sure it will be in next versions...
