I am running Debian "Jessie". When I go on websites that are heavy on flash (I'm not sure how to describe it) like skype's website, Konqueror crashes and my desktop blacks out for a few seconds and then takes me to the login screen. On other websites like LQ, Konqueror runs fine. I noticed when I execute Konqueror via terminal I get the following output:

Iceweasel also has the same issue but when I open it using terminal I get:

GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

When I run chrome, chromium, and opera via terminal I do not have any problems. And they don't crash on websites that use a lot of flash. Does anyone know if the error I am receiving from terminal related to the crashes? Thank you.

This has nothing to do with flash!

Mime type is MS Office.

That makes sense cause I was wondering how would this effect flash in any way. But now whats going on with flash is a bigger mystery. Showckwave player is always activated in iceweasel. So I don't know why iceweasel is having the same problem.
