With 6eed4c4241ae30f9e0af2581555c5ce6c25623f3, I get:

so the spam is fixed, though that internal crash seems nasty...

does winedbg on a test app (like winemine) shows the same issue ?
if so, what's the output of winedbg --gdb winedbg winemine
(using gdb to get a backtrace of failing winedbg)

A+

If I do:
$ wine winedbg winemine
with wine installed it /usr/local, works fine, but doing:
$ ./loader/wine winedbg winemine
WineDbg starting on pid 002e
winedbg: Internal crash at 0x7eefd19c

Adding --gdb doesn't help much:
002e:002f: create process 'C:\windows\system32\winemine.exe'/0x110738
@0x7ef78800 (0<0>)
winedbg: Internal crash at 0x7eef519c

doesn't seem limited to 4.6.0 though, I get the same with 4.4.5. Weird..

Ignore, bad patch in my tree, sorry for the noise.
