Comment 1 Christophe Marin 2011-10-12 23:48:10 UTC

we found a way to get the malloc issue this evening:

rmb on a folder / properties / view tab / changing the displayed name twice triggers the issue

Comment 2 Denis Kurz 2016-09-17 11:09:01 UTC

Closing due to lack of activity for 5 years and kmail(1) being unmaintained for a long time. Also, the actions suggested in comment 1 do not trigger a crash any more.
