Aw, snap when searching with omnibox on chromium

For some days now I get that annoying "Aw, snap" window when I try to search with the omnibox in chromium. What I tried so far:
- clear /tmp
- rm ~/.config/chromium
- rm ~/.cache/chromium
- install another version (19, 20, 21..)

Nothing helped. In a fit of despair I rushed to the settings and checked "Enable Instant for faster searching" (even if I really really don't like that feature). This seems to be a good workaround because the "Aw, snap" page stays away...

Nice Slackbuild on Github, frequently updated:

Edit: Don't forget to replace make with make -j2 in file chromium.SlackBuild on a dualcore system to use both cores. :)
