Bug 92878

Version:            (using KDE KDE 3.3.1)
Installed from:    SuSE RPMs

I'm using KMail with a local SMTP server (postfix 2.2_20040616).

I created a new e-mail message and attached two mp3 files of about 5 MB in size, resulting in a message whose encoded size was about 14 MB.  KMail began slowing down significantly as I was selecting the files, and by the time I clicked on the send button, performance was very poor.  The message window did not disappear until about a minute after I had hit the send button.  Shortly thereafter, I received the following error dialog:

Sending failed:
Sendmail exited abnormally.
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.
The following transport protocol was used:
Sendmail

Since KMail was significantly degrading system performance, I tried to close it, and KMail crashed with the following backtrace:
