Summary0000231: crash log when browsing complex data structure in Komodo
DescriptionI've run across a semi-reliable crash when browsing complex data structures ( eg a large simplexml object ) in Komodo 4. After while of browsing through the data structure, the session quits and I get this dump:

I tried to reproduce this with rc3-dev, but I can not manage to reproduce it with a 3mb XML file. So I would need slightly more information: a script and the remote-debug log would be most excellent.

regards,
Derick

Thanks for the reminder, I'll have a look at this issue again today with our latest K4 builds which IIRC are using rc3-dev.

this seems to be fixed in rc3-dev, I can't repro anymore. =)
