 |

I've been using Arson without problems for a while now, but it has suddenly stopped working. The only thing I can think of that I've changes is a revision of the latest Qt. I've remerged Arson, to no avail.
Here's some strace output:

Any ideas? It's the only CD writer I can find that will make Audio CDs from oggs! |

I also get this backtrace in the KDE crash handler:

Have you recently upgraded to the new kde?
I was having problems with arson (and other kde programs...) segfaulting because for some reason the new kde is in a different slot, which causes problems if you don't manually uninstall the older libs.

| Well I upgraded to KDE3.1 about a week after it was announced, but I'm fairly sure I've been using Arson without any problems since then. The only thing I can think of that would affect Arson is Qt, and it seems to be Qt widgets being called be libkdecore that are causing the crash. I've tried remerging qt-3.1.0-r1 and r3 to no avail. I might try downloading an emerging qt-3.1.1 sometime. |

Hmm... I am not sure what the problem is but just make sure you only have the 3.1 version of the kdelibs installed. By default portage tries to leave the old 3.0.5a libs installed (which borks kde apps.)
If you haven't already, do this:
| Code: |
emerge unmerge kdelibs-3.0.5a

| Well I unmerged the old kdelibs, and it didn't work. I tried remerging arson, and it still didn't work. I get exactly the same error message :-/ |

I had this problem too, and can only add that the issue went away. 
I had not tried it for quite a while, had emerged and worked with cd-bakeoven and k3b for a few burns, with several emerge -puD worlds in between. Tried Arson again a few days ago, and it worked!
I am running an '~x86' system although am _not_ offering or suggesting that as a "fix".
If I knew why... |

| Same here - it just started working when I got around to it in a emerge -u world. I suspect it was because I re-merged qt, kdelibs and kdebase (in that order) for rc upgrades. |
