In the debugging output there are a lot of lines like "#1 0x0000000000000002 in ?? ()" and "(no debugging symbols found)..." because the debugging symbols are removed unless FEATURES="debug". Also, this package has optional debugging support which isn't enabled because you don't have "debug" in your USE flags. Could you re-emerge the package with the following command: # FEATURES="debug" USE="debug" emerge museseq and then post the results of running the program in gdb.
I just re-emerged museseq using 'FEATURES="debug" USE="debug" emerge museseq' and got this trace when run from gdb: gdb museseq GNU gdb 6.0 Copyright 2003 Free Software Foundation, Inc.

There is definitely something fishy going on.... When quitting museseq I get a '*** glibc detected *** double free or corruption (!prev): 0x0000000000867150 ***'
