Description ZJ Laczik 2007-04-03 12:25:05 UTC 
Version:           1.9.4 (using KDE 3.5.4, compiled sources)
Compiler:          Target: i586-mandriva-linux-gnu
OS:                Linux (i686) release 2.6.17-5mdv

When trying to load/preview an e-mail I recently received, which had more than ~30 attachments and was ~4MB in size, the system locked up completely after some initial disk activity. A system reset was then required.  I view this as critical - KMail must not bring the whole system down, even if the e-mail it receives is extremely large or complex.

When trying to access the same e-mail on a different machine with more HW resources (but the same software setup), the system froze again for a few minutes with heavy disk activity, probably swapping, but then came back to life with the following message from KMail:
'Error while retrieving information on the structure of a message.'
'The process for the imap://imap228.herald.ox.ac.uk protocol died unexpectedly.'

A different e-mail from the same sender, so probably sent from the same client and having the same internal structure, but only with 8 attachments and ~2MB size, did not cause any problems.
