Did some searching for something similar but was not successful in finding what I thought would help.
Running Mint 5 on a new core 2 duo system. Runs fine. I copied some text with a couple pictures from a web page and pasted into a new writer page. It pasted and then immediately crashed (writer closed) and gave me the notice about recovering the file. File recovery didn't work. It would just crash again. I thought that maybe the tmp folder was not large enough so I went into tools, options, path and set the tmp path to the /home/name/tmp folder that I created. I figured that my home file might have more space for the temporary file.
Alas, this didn't help anything. Has anyone else run into this problem or does anyone have an idea of something else to try?
