Package: sylpheed
Version: 3.7.0-8
Severity: important
X-Debbugs-Cc: [email protected]
Dear Maintainer,
* What led up to the situation?
Tried to read a typical Github notification email.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Clicked on the unread message in the message list window.
* What was the outcome of this action?
Sylpheed became unreportable at all, CPU usage was 100%.
I had to kill the program manually from a command line.
* What outcome did you expect instead?
Just displaying a mail.
The message which caused this strange behaviour is a regular
Github notification. What I did before reporting the
bug:
1. I found that message in the mail folder and tried to distill
the minimal example by removing headers or body lines,
but didn't found any obvious pattern.
2. I compiled Sylpheed from Debian sources and then run inside
gdb. Seems it's some bug inside GTK, like endless loop of
signals. I can break the program (Ctrl-C), inspect the backtrace
and continue, and then break again. Please see the sample
backtrace below: the last function from Sylpheed is
`summary_select_row`, then only GTK functions are being called.
What I observed is that rarely the mail is displayed on the
screen, and then program stops responding. Usually there's
blank message window.
I have a custom GTK theme set via `export GTK_THEME=Blackbird`.
Please drop me a line and I'll share with the maintainer & developers
the problematic message. It contains mails, logins, names, etc.,
don't want to publish them in the bug report.
best regards
Wojciech Muła
