--- Comment #11 from Dmitry Timoshkov dmitry@baikal.ru --- (In reply to Bruno Jesus from comment #10)
This bug is older but Dmitry did the analysis of the problem in bug 38400 and I believe we don't need two bugs opened for the same issue, so resolving as duplicate.
*** This bug has been marked as a duplicate of bug 38400 ***
I'd suggest to keep this bug separate from bug 38400. Although the symptoms are similar these two are really distinct bugs (and two separate fixes): one for A another for W implementation of the GetSaveFileName API, moreover the bug 38400 also needs a fix to GetOpenFileNameW, and it's a coincidence that the same fix works for it as well.
