Created attachment 2206 [details] problematic mail while reading a specific mail claws hangs indefinitely, cpus goes to 100%, no dialog to stop claws appears, claws needs to be killed. looking at where it is stuck by means of "claws --pid ", it appears that most of the time the applications is somewhere in pango, I intercepted it at the following points: pango_default_break() pango_find_paragraph_boundary() ../sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S I attach the said mail.

Your attached mail displays fine here, (as expected). Several users have reported this problem, both on this bug tracker and elsewhere. Every time the suspect message displays fine for me. It could be pango, (it's not Claws Mail). Presumably, on debian, you are using version 1.46. Here I am using pango 1.48. *** This bug has been marked as a duplicate of bug 4430 ***
dear Paul, yes, my pango version is 1.46.
