Summary: Regression: regedit crashes when trying to edit a string
                    value with theming enabled.
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gui
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

With latest git and 0.9.13, regedit crashes with enabled theming. This worked 
fine with 0.9.11. The interesting part of the backtrace (yes I should better 
attach it but it's only 6 lines)

Unhandled exception: page fault on read access to 0xffff0024 in 32-bit code 
(0xffff0024).
Backtrace:
=>1 0xffff0024 (0xffff0024)
  2 0x7e968b36 subclass_proc0+0x77(wnd=0x20032, msg=0x14, wParam=0x254, 
lParam=0x0) [dlls/comctl32/theming.c:89] in comctl32 (0x7e968b36)

This didn't happen in 0.9.11. The regression test will follow although I 
assume it's related to one of the patches starting with
