[Seaside] Seaside 2.8.4 image crashes [newbie]

[Ivar Refsdal]

Hello all,

I'm a very fresh newbie, so the problem could just be myself.
Apologies in advance
if that is the case. However I'm getting a crash when doing the
following after starting Seaside with ./seaside.sh:
First going to http://localhost:8080/seaside/magritte/editor in a web browser,
then clicking 'Add' and then 'Save' without entering any data.
Then when clicking 'Preview' Seaside crashes with the following message:

Segmentation fault

I'm using this image file (no changes made):
http://www.seaside.st/distributions/Seaside-2.8.4.app.zip
Otherwise I'm on Ubuntu 9.04 i386, nothing special. Let me know if I
can provide more details.
I also tried executing the cleanup commands in the workspace, but it
didn't help.
The crash does not occur with the previous image I tried: Seaside-2.8-578.app.

Any suggestions?
Thanks,

Kind regards,
Ivar Refsdal

(First post, hope everything went well.)
