--- Comment #4 from Rafał Mużyło galtgendo@o2.pl --- There is something interesting in the log:
0024:trace:file:CreateFileW L"Z:\home\grey\app\cherry_1\cherry-files\\97f3\697d_02.CH" GENERIC_READ FILE_SHARE_READ FILE_SHARE_WRITE creation 3 attributes 0x1
Note the name is a letter short. While debugstr_w does truncate its output, it still has 300 byte buffer - that's nowhere near it.
In this log there seems to be nothing in between where the path has been retrieved correctly in unix format and when it appears truncated in Windows format.
Perhaps add 'nls' to WINEDEBUG ?
