Description Jacopo De Simoi 2009-03-27 19:40:41 UTC
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

After checking out rev944751, konqueror crashes whenever I hit "/" to search text in the page and then press a key (to start searching).

Reverting the patch solves the issue.

Comment 3 Jacopo De Simoi 2009-03-27 23:35:07 UTC
Superfast fix, thanks!

This bug sneaked in right in time for 4.2.2 tagging - who should we bug to have it fixed before release? Dirk?

that's thanks to your faster report ;)

I don't know if it's needed... it's a debug assert, it won't affect release builds.
Comment 5 auxsvr 2009-04-03 20:28:29 UTC
I think I hit this with 4.2.2, I can trigger it reliably with long webpages after pressing "/", entering phrase to search, then F3 several times:

@auxsvr: you crash looks more like bug 189201. Which may also be related to this
