Incomplete Session Restore (beta 005) Missing All Suspended Groups!

[GoogleCodeExporter]

I have 15 groups: 1 ACTIVE and 14 SUSPENDED groups. Totalling around 200 tabs 
spread over the various groups. I manually export my session file (around 800 
kbyte) as a backup.

When I manually restore this backups back to FF, then ALL SUSPENDED GROUPS are 
lost. Only the active group are restored.

This is with the newest beta 005!!

When I activate several groups and manually export it, then restore it back, 
again: only the active groups are restored.

FF 32.0.3   TGM latest beta 105 (005)    Win7 64 bit, 16GB ram, SSD
No plugins except adblock plus and adobe flash, without which I cannot imagine 
any FF user could use TGM! So this is a big problem for us TGM users indeed, 
and its easily reproduced.
