Its broken on a NSLU/debian LennyLe with svn-1696 mt-daapd:
2007-11-14 22:14:22 (40020f40): Serving 4336 songs. Startup complete in 11 seconds
2007-11-14 22:14:38 (40cf84e0): malloc error in vasprintf
2007-11-14 22:14:38: Aborting
Interestingly mt-daapd-svn-1586 does NOT show this bug, nor does your swf v0.2 cause the crash.
Amazing, have you been trying to write a remote DOS script for mt-daapd-svn-1696? LOL*
It seems version v0.3 of your swf is precisely incompatible with svn-1696, but svn-1586 works flawless as does v0.2 with all mt-daapd version.
