Created attachment 1431 [details] This is the runtime error I get. I'm not sure what causes this, but sometimes when I try to read an e-mail, I get the attached runtime error. This has happened in 3.9.3 and 3.10.1 (just upgraded last night). I'm sorry I can't tell you more, but claws doesn't tell me much more. I can be reached by phone at 313-368-0791.
This has been fixed in 3.12.0-1.
