KCategorizedView bug?

[Andreas Pakulat]

Hi,

I can't help you with the use of the class, but you should improve the
bugreport a bit. First of all, don't use paste's, either attach files to
the bugreport or put the code and backtrace inline. The paste's may be
deleted and then the bugreport is useless.

The other thing I noticed is that the backtrace does not match your sample
code, it refers to MyModel::data() line 58, but in the paste in line 58
there's already the KApplication constructor. So please make sure you post
the exact code that matches the backtrace, not some other version.

Andreas
