Description Daniel Richard G. 2009-02-03 02:33:02 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

I came across an odd Web page, in Google's Shopping search results, where any attempt to leave the page would send me back to the same page. Even after hitting Home, the browser would boomerang back.

Frustratedly, I hit Home several times in rapid succession, and the browser crashed with

#8  0x00007f4d2ec56932 in ~Interpreter (this=0x7f84750)
    at /home/kdesvn/kdelibs/kjs/interpreter.cpp:266
266         ASSERT (m_startTimeoutCheckCount == 0);
(gdb) p m_startTimeoutCheckCount
$1 = 1

This from from a source tree at r917938. I've saved a core file, in case anyone would like me to poke at this more.

Comment 1 Daniel Richard G. 2009-02-03 02:45:42 UTC 
For reference, the Google page in question:

http://www.google.com/products/catalog?q=kensington+expert+trackball&btnG=Search+Froogle&cid=8301514163452884180&sa=title#ps-sellers

If you click on the name of a vendor (e.g. Newegg.com), the page basically reloads. Oddly enough, this happens the first and second times you click, but not the third.

I cannot reproduce the original behavior, where this would also occur after hitting Home (and no third-time's-the-charm bit either).
