#1 segv in createTagEditor

[Joe Oldak]

Using version 1.1alpha

I've been trying to write a python program that goes
through my collection of mp3s and oggs, and rearranges
the directory structure based on artist/album etc.

I seem to run into problems if I try to process lots at
a time. In this case, I got a segfault. Here's a trace
from gdb:

Program received signal SIGSEGV, Segmentation fault.

I know that it had a problem extracting artist/album
info from this track.

It crashes in the same place every time if I run it
over my entire collection. If I run it just on this
directory of mp3s it's OK.

Perhaps it's just running out of memory or something?
Though I'd have hoped for something a little more
polite than a segv :)

Since I speed up development of libtagedit only very lately (I struggled
and thought of dropping this project in favor of something else). I did not
have a look at this yet. In fact, I did not check the project page for quite
some time. Once I cleaned up the build system, I will make some intensive
tests whether it's possible to reproduce bugs while scanning of a large
amount of files. I'll try to use valgrind, too, to check if it sucks up to much
memory. Once I finished the tests, I will release a new 1.1 beta release,
which will hopefully not have this bug.
