 I triggered this problem on sugar-jhbuild during some clipboard (crl+c,
 ctrl+v) interaction. Sugar crashed and the output says the following:

 Bert had simillar problems while doing:
 {{{
 <bertf> was trying copy and paste ... it crashed when i did ctrl-c in
 write. but I copied a bit of stuff between browse and etoys before
 }}}

 And another time Bert discovered that ctrl+c in etoys crashed sugar too.
 So we need to find a consistent way to reproduce this behavior.
