Bug 201701

Can confirm with trunk: Reproducible with the following:

send a larger mail, which takes some seconds to upload. During upload, double click the mail in the outbox folder to have it open in a composer window.
Wait until the upload has finished, then close the composer window -> crash:

I have a bit (one-step) more exact backtrace it seems:

#5 0x00000000031b9ec0 in ?? ()
#6 0x00007f0e7c72312d in KMMessage::transferInProgress (this=0x38c3c80) at ../../kmail/kmmessage.cpp:270

Any idea how to resolve that
#5 0x00000000031b9ec0 in ??
part?

Thank you for your report. Kmail1 is currently unmaintained and the code has changed sufficiently in Kmail2 so the backtraces are not really useful anymore. Should you experience the same crash in Kmail 4.8.5 or later, please open a new report for Kmail2. Thank you for your understanding
