AW: [Qgis-user] splitting polygons

[Hugentobler Marco]

Hi Micha

Do you have the possibility to test with current svn version?
I recently fixed a feature splitting bug that occured in connection with geos2 library. I think this is the same one you described.

Regards,
Marco

Hello Jurgen
Here's what I did:

Went to a second Ubuntu machine (8.04), running qgis Metis 0.11, (just 
to make sure the crash I got before with 1.0.0 wasn't just a fluke. ) I 
created a simple polygon shapefile. Then I used the split polygon tool 
to split one feature - no problems.

Next I did the upgrade on this machine to get 1.0.0 Preview II. I now 
ran the new qgis with strace, opened that same shapefile, and tried to 
split one of the polygons, and got the same crash as on the first 
machine. Here's what appeared on the console:

and I put the resulting trace here:

Thanks for your help.
