Look like it's crashing far inside gecko. Even though you're on a scrollbar, drag&drop is triggered but it has no window, and end up with a null pointer reference ...

It happens to 1.6b2, also when you are viewing errors on kmm files.

Yes, I can still see this bug in 1.6b2, makes debugging pretty painful.

Patch here:

Can't test the patch. With the new gklayout.dll (removed xpti.dat and compreg.dat) applied, K-meleon doesn't fully open. The result is a window with all bars (bookmarks, scrollbar, status bar, etc) but with a transparent content window. The crashreport plugin can't catch the error, because there isn't, but when you restart K-meleon, it request to restore last session, as if it crashed.

Yes, K-Meleon 1.6b2 isn't functional with this DLL.

Well sorry, this is for 1.6b1, I dind't know that 1.6b2 has a different GRE

K-Meleon 1.6b1 console2 is scrollable with this DLL.
The symptom is fixed but not so the cause.

It works if window.content is not null.
Calling viewSource with type="chrome" prevents the crash,
enables goToLine, ...
