This question exactly describes a problem I'm having that makes my system unusable https://askubuntu.com/questions/140028/12-04-occasionally-freezes-when-image-viewer-opens-pictures-possibly-graphics-d
The question was "closed" with a note that it was a bug and needed to be reported as such. I assume it was reported as a bug by the original questioner or someone else who experienced it. How can I locate the existing bug report related to this question and find out if there is a fix or workaround. As with many others on this board, I do not know how to categorize the bug, and I am intimadated by the amount of technical detail required to report a bug; I just want it fixed.
