To complete the story, I had all the symptoms Sebastian described
until a certain time and then it simply worked...

Another strange thing : I can now run SimpleAgenda without problem
under WindowMaker but, if I use fvwm, I get all the errors above
again. If I start the application under WindowMaker and then switch to
fvwm, it continues to run happily....

I *think* this might be due to code ordering and timing problems but
for now I have no clue.
