Muse won't start in Karmic

[Steve Batte]

I just installed 9.10. When I click the Muse icon nothing happens. If
I start from the command line I get this scary C-looking stuff:

muse: malloc.c:3074: sYSMALLOc: Assertion `(old_top == (((mbinptr)
(((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct
malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size)
>= (unsigned long)((((__builtin_offsetof (struct malloc_chunk,
fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t)))
- 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end &
pagemask) == 0)' failed.
Aborted

I tried a bunch of different flags, muse -D, muse -a, -M etc, same
results every time. Even -v

I'm on an Athlon 64 bit 3gig processor, 3 gigs of memory.
