I had the very same problem. Actualy digging and digging and digging in a lot of forums, I found that the error has to do with pcmanfm. The file manager is broken, and even if your mime-types are updated, it will not recognise *any* file (pcmanfm does also manage the desktop).
The solution I found was to download version 0.5.2 from: http://sourceforge.net/projects/pcmanfm/ And compile it. It is necessary to install various development packages (hal, hal-storage, gain...) through Synaptic. $ ./configure $ make It will complain about a missing '\n' in the translation file ca.po. cd into po and enter the command: $ pico +298 ca.po In the previous line, add a '\n' before the last '"'. $ cd .. $ make $ make install $ cd /usr/bin $ sudo ln -fs /usr/local/bin/pcmanfm $ killall pcmanfm Press [Windows]+R and type: "pcmanfm -d" Everything should work now. The obvious fix to this error is to upgrade package in Ubuntu. -- file icon handler doesn't remember the file association https://bugs.launchpad.net/bugs/456266 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list universe-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/universe-bugs
