Description Henri Valta 2013-08-31 08:27:27 UTC

clicking the message or even hovering mouse over it until the tooltip shows, crashes kmail.

Message in the folder view shows chinese characters in subject and sender. Seems to be gb2312 encoded.

I'll try to attach the message and partial backtrace here. Creating full backtrace seems to take a bit of work on arch... I'll create it if required

Reproducible: Always

Steps to Reproduce:
1. try to view or hover mouse over the message in message list
2.
3.
Actual Results:  
crash

Expected Results:  
no crash

Using kmail 4.11.0-2 package on arch linux 64bit

Turns out this is caused by fontconfig package upgrade to 2.10.94-1. Downgrading to 2.10.93-1 fixes the crash. Any message with chinese characters seems to cause the crash with 2.10.94-1

Is this a bug in fontconfig or kmail bug exposed by new fontconfig?

Wow, thing are moving fast.
fontconfig update to 2.10.95-1 resolved the issue again and fontconfig changelog has this:

    Fix a crash

So I think this should be just closed
