I have a stable gentoo system, so atm I run:

I tested also:

When I run kmail, it crashes and in dmesg I see:
[ 3514.679879] nouveau 0000:03:00.0: gr: TRAP ch 5 [003fb74000 kmail[23649]]

[ 3514.680191] nouveau 0000:03:00.0: kmail[23649]: channel 5 killed!

If I compile kmail with the debug stuff I get what is in the kmail-debug attachment.

If I compile also libdrm with the debug stuff I get a double-free which is in the double-free attachment.
