#3 application crashes upon data store creation

[Ralf Hauser]

ok, I
1) imported a certificate (without a private key)
2) attempted to create a data store and during the
third step where I was asked to select a certificate,
only blank was shown and no certificate, but I could
click the next button anyway, and then the application
was gone.

Unfortunately, it didn't even produce a stack-trace on
std-out...
