Description Allan Sandfeld 2018-02-02 18:45:59 UTC 
KMail now consistently crashes when I click on my spam folder (which somehow also got itself changed to "act on new email"). 

The backtrace shows it is a recursive loop and probably a stack-overflow. It has more than 4000 entries that all look the same:

Thread 1 "kmail" received signal SIGSEGV, Segmentation fault.

I haven't found the bottom. The kmail version is 17.12.1 from neon.

Ah, found the bottom, I thought for a moment gdb was also in some infinite loop:

Comment 2 Allen Winter 2018-02-02 22:40:29 UTC 
I also have this happening quite often.
Coincidentally I made a little patch last night to address it.

I'll put up the patch on phabricator so you can test.

this is a dupe.
