The two-channel auto-type obfuscation feature of KeePass doesn't work for me with Chromium (on Ubuntu 12.04 64 bits). However, it works just fine with Firefox.

Dows anyone know how to fix this?

Textboxes in web forms in Chromium seems to have something special that causes this feature to fail. Only some of the username/password characters are being auto-typed.

This might be related to this: if I select an entry in KeePass and click "Copy User Name", I can paste it fine with Ctrl+V in any textbox in Firefox, but I can't on Chromium. However, text copied using Ctrl+C from a regular text file (say, from gedit), can be pasted fine on both browsers.

What may be wrong?

I wouldn't like to deactive this feature for all the entries in my keepass files as I use them on Windows too and they work just fine there (even on Google Chrome for Windows). This feature gives an appreciated extra security measure against spyware/keyloggers.
