Hi all,

Beware, maybe the following is only my fault as with the NSTabView...

Anyway, I'm having troubles when invoking services with latest svn. As
an example, trying 'Make thumbnail(s)' in GWorkspace results in 

Program received signal SIGSEGV, Segmentation fault.

This is on x86_64 with gcc 4.2.4, libffi 3.0.9 and libobjc2.

I tried without libobjc2 with different results : instead of a crash,
I get a warning about a missing method or a too old libobjc, I didn't
save the message.

When the service is based on an application (Terminal or SimpleAgenda
for example) the application is launched correctly and then the
calling application crashes.

Anyone seeing something similar ? Any hint ?
