faulty mail which makes litehtml crash

Hello,

I just received a spam which, if viewed with the litehtml plugin makes claws
mail crashes with a segmentation fault. Tested with a fresh profile with only
litehml plugin activated and only this mail in the inbox.

I'm using claws mail 3.17.4 on mageia 7 x86_64.

here is the backtrace with gdb, the guilty mail is attached:
