It seems your system is broken, libc6 corrupted, ram defect or something like that I guess.

Daelstorm, what do you think about it ? (Feel free to close the ticket...)

[daelstorm]

I've emailed him, but haven't gotten a response yet. I guessed it might be a buggy version of libxml++2.6, but I've no way of knowing for sure, yet.

Hi,

I had the similar issue in my slackware-current system with both museek+ versions I'd tried - 0.1.2 and 0.1.11. Original museek from svn never had that issue (including versions with seeschloss patches). Did a backtrace and it pointed to the code inside museek+ dealing with libxml - build-i686-linux/Muhelp/Muconf.cc:42. So I upgraded libxml++-1.0.4 (from linuxpackages.net) to libxml++-1.0.5 (self-compiled). And after that it started to work like a charm. I suspect my libxml++ installation was corrupted. So I'd recommend anyone having a similar issue to try to upgrade or reinstall the libxml++ library first.

Rgds, headphone

libxml issue.
