I'm testing KDE 4.4.4 on my Apple Power Mac G5 ARCH=ppc64 (bug #308903 comment #13 onward).
KMail freezes for me in the composer window in two cases:
1.) after a short time period, when text is already entered.
2.) when clicking the send button (if not case 1 was first).
Both the main KMail window and the composer window are task switchable (redrawn when getting the focus) but mouse and keyboard user action is completely ignored. The cursor in the composer windows is blinking at the last working position.
When the freeze occurs, I see the following message repeated every second in the console:
kmail(14388)/libakonadi Akonadi::SessionPrivate::socketError: Socket error occurred: "QLocalSocket::connectToServer: Invalid name"
Steps to reproduce: Start KMail, compose a new message, write some text, wait a minute or two or click the send button. Watch console output.
I've searched for similar bugs, but none is completely the same:
This KMail crashes, mine doesn't.
* Bug #304895 is also different. I no longer have this Akonadi Server Self-Test window.
BTW the freeze of my KMail occured before with the Akonadi Server Self-Test window, and now without it – in both cases with the same console messages repeating every second and completely freezing KMail.
The CPU usage is normal in my case, whereas I read in other bug reports that Nepomuk and Akonadi may be utilizing the CPU at close to 100%.
I copied an existing (older) configuration for my KDE setup. My KMail configuration files are from KDE 3.1 or so, and got updated with every new release. This can be seen in the configuration files like this:
These older configuration files may also play a role in this issue.
I'll try a fresh KDE setup next and report back. (May take a while, I've *real* work to do now…)
Due to an unforeseen event I no longer have my Power Mac G5 2.0 GHz Dual-Core “Late 2005”. It is now at my sisters' and runs Mac OS X again.
I still hope that the 64-bit PowerPC architecture will continue to be supported, since I intend to get my G5 back in a few years. It will then be running Gentoo Linux again, as long as it (the G5) is not broken, because Apple will by then no longer have a supported operating system that runs on PowerPC based Macs.
