Bug ID: 361109
Summary: kmail freezes with high cpu usage when sending signed
messages with attachments
Product: kmail2
Version: 5.1
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: crypto
Assignee: kdepim-bugs at kde.org
Reporter: christopher.suttles at gmail.com
When attempting to send an signed pgp message with attachment (8MB PDF), kmail
prompts with a message box that asks "Some parts of this message will not be
signed. Sending only partially signed messages might violate site policy. Sign
all parts instead?" At this point, CPU usage hits 100%. System becomes frozen,
however mouse is still useable. Clicking "Sign All Parts" does nothing, however
clicking "Send As Is" sends the message in unencrypted form after nearly 1-2
minutes.
This seems to only happen with large attachments (greater than 5MB or so).
Reproducible: Sometimes
Steps to Reproduce:
1. Attempt to send signed pgp message with attachment
2. At "Unsigned-Message Warning" dialog box, cpu hits 100% and system partially
freezes
3. Can only send the email successfully if "Send As Is" is clicked.
Actual Results:
Can't send emails fully signed. Getting high cpu usage and kmail become
unresponsive for some time.
Expected Results:
Email should be able to be sent as normal, with minimal cpu usage (or none).
