Description

I have a point feature in which one of its attribute has a few nulls. After I click on Classify using the Categorized renderer, I get a segfault: http://pastebin.com/CDxBC4ma . If I replace these nulls with something else I do not get a segfault. I am using "Quantum GIS - 1.9.90-Alpha 'Alpha' (956995c)" on 64 bit Ubuntu 11.10

Does not happen with the attached test layer. Please attach a sample data that causes the problem.

I was able to view your file just fine, but when I classified the teste attribute, qgis crashed. So, I am guessing that classifying integer fields are fine, but classifying text will cause a segfault.

Then it should be something in your local installation, as I use also Ubuntu 11.10 64bit and qgis master.

Can you check on another machine? do a clean install?

I take it that you were able to classify on the attribute teste without a crash? What revision are you using? I'll clean up my system and do a fresh install and report back.

Thanks for making the suggestion to make a clean build. After a make clean and uninstall, I rebuilt qgis and restested the teste.shp file. There are no more crashes, so I'm closing this bug report.
