[Gambas-user] My Gambas2 is broken!

[M0E Lnx]

I've installed Gambas2-2.0.0 and used it several times on this box
(running Vector Linux 5.9 Gold).
Suddenly I closed it, like always, and then when I tried to use it
again I get this ugly error

moe:$ gambas2
moe:$ Design.Init.37: Cannot create input fifo
0: Design.Init.37
1: FMain._new.25
2: Project.Main.157
WARNING: circular references detected
FMain (1)

After that, the program exits.
Anyone seen this? How do I fix this?
