[Vm-dev] ExtendedClipboardPlugin seg faults on Fedora x86_64 ?

[David Corking]

I am not sure if the following is a Fedora Linux packaging problem or
my own error. However Bert suggested it may be
ExtendedClipboardPlugin, so I wonder if you can make one or two
suggestions for deeper investigation, please.
David (AFAIR this is my first post on vm-dev.
SoaS is Sugar-on-a-Stick - a spin of Fedora with the OLPC software.)

Sounds like a problem in ExtendedClipboardPlugin. That would be best
reported on vm-dev, or squeak-dev.
