Workspace unable to login: wvw_flow_security broken?

Question

I have a really nasty problem with my local APEX environment.
It is not possible to login to any of my workspaces.
When I enter my workspace, username and password and press login I first get a time-out from my browser (Chrome calls it Error 324(net::ERR_EMPTY_RESPONSE): Unknown error). When reloading I get:
"Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.Error ERR-7621 Could not determine workspace for application (:) on application accept."
(I don't think it's related to the problem though, but it might be helpful in finding the source of the problem)
Logging in to Admin is no problem though, it only happens when logging in to any of my workspaces.
I'm running APEX 3.1.2.0.12 on a 11.1.0.7.0 database on a Windows XP 32-bit, so the latest possible versions of everything.
The problem occured 2 weeks ago. This morning I decided to install the 3.1.2.0.0.12 Patch to try and solve it to no avail. But in the logging of the install I noticed something interesting:
declare

"APEX_030200.WWV_FLOW_SECURITY" After the installation was done I checked the wwv_flow_security package, but it's valid then.
Can anyone explain this behaviour and help me out here? Are there things I can check?
Many thanks in advance for taking the time.

Hello Michel,
From the documentation (http://download.oracle.com/docs/cd/E14373_01/relnotes.32/e13365/toc.htm) :
4.1 Problem Applying the Oracle Application Express 3.2.1 Patch Set Against Oracle Database Release 11.1.0.7
When applying the Oracle Application Express 3.2.1 patch set against an Oracle Database release 11.1.0.7, you may encounter the error ORA-00600: internal error code, arguments: [kgiinb_invalid_obj]. This will be recorded in the generated patch set installation log, apxpatch.log.
Workaround:
If you encounter this error, you should download and apply the patch for database bug 7420394 from Oracle MetaLink, and then attempt to install the Oracle Application Express 3.2.1 patch set again.
