I found how to recreate this bug (it's pretty easy when you have the code to look at :-) ) :
1. open software-properties (gtk/kde). 2. select 'add CD-ROM' button (with no CD in the drive). 3. wait for an error message box (because there's no CD in the drive). 4. press OK to dismiss the message box. 5. At this point, the app is pointing to an invalid temporary sources list, so any action that modifies the sources list will result in this error. For example, go to the first tab, and toggle any component - the error is reproduced. (if anyone sees this happen when there's no CD-ROM actions involved, please speak up!) -- software-properties-gtk crashed with IOError in save() https://bugs.launchpad.net/bugs/221667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
