Dragging link from choqok to Chromium reliably crashes both.

One thing I do a lot is drag links from Choqok (a KDE twitter client) to Chromium. Sometimes I drop them in the URL textbox so that the link opens in the current tab, sometimes I drag it to the tab bar so that it opens in a new tab (I wiggle the mouse a bit until the small arrow in the tab bar shows up, indicating that Chromium will open a new tab).

After I repeat this a number of times (haven't counted, about 10?) Chromium always crashes. Recently, I noticed that Chokoq is crashing too. I was under the impression that it didn't crash before and it now does, but I'm not sure. In any case, with Choqok crashing I was able to get the following backtrace:
