Sourceforge shows only attachment of my previous message instead of

Hi Oliver,
warnings and crash are not related.
As I remember my debugging, decodeColorTable is sometimes called with
maxcolor=1<<16. This results in a series of warnings.
I reproduced the crash and include the output of gdb. Full output is in
attachment.

Vector fonts has size 5 but index lbl->type=7. I don't know why, so I
simply increased the size of vector to maximum possible value of
lbl->type. It is always masked with 7, when assigned.
