In the 'Encoder Config' tab, I'd set the 'encoded file location' path to ~dump-drive/%artist/.... This path doesn't exist. KAudioCreator didn't show a warning message, but wrote all files in /tmp/kde-username instead. The program didn't execute the encoding steps, but also didn't give an error message about a failure. (my encoding type was set to "Leave as wav") As soon as the /tmp partition is filled, kaudiocreator gives a "Disk Full" warning, and continues with the next track. Reproducible: Always Steps to Reproduce: 1. Use a small partition for the /tmp folder 2. Set the 'encoded file location' to an invalid location. (perhaps set the encoding-type was "leave as wav") 3. Rip the tracks.
Can you report the problem directly at http://bugs.kde.org/, please, as this Bug seems to be in the application itself, not in the Gentoo-Packaging.
kaudiocreator always used the default temporary path to store wav files (before moving them to the destination dir, I believe). But now it lets you change the temporary path (in kde cvs): http://bugs.kde.org/show_bug.cgi?id=74522
closing as upstream issue.
