Hi. The Launcher does not launch the game for me. It downloads minecraft and modpack but when I hit "Launch" it just closes. I'm running Fedora Linux 64 bits and standalone modded minecraft works fine.

My FTBLauncherLog.txt is here: http://fpaste.org/Lwu4/

I'm a programmer (not a java-programmer though), so I tried to debug it myself using some tools. The only appropriate tool was the /usr/bin/strace. Found some strange unsuccessful syscalls like
Code:
lstat("/home/legolegs/games/minecraft/FTBMP/FTB_Launcher-0.2.1-Beta.jar;", 0x7f2fc26f4490) = -1 ENOENT (No such file or directory)
(note the semicolon). I don't know if it is related or just some useless java subsubsubsystem derping around.

Dear ftb launcher developers, can you please help me with that?
