Sure enough!  I reproduced it simply by
* wine/programs/notepad/notepad
* File / Save As
* Navigate to Desktop
* Select root directory
Bam!  
=>1 0x7b362ca3 DPA_GetPtr+0x27(hdpa=0x4001, nIndex=0x0)
[/home/dank/wine/dlls/comctl32/dpa.c:479] in comctl32 (0x7b90e150)

if (!hdpa)
        return NULL;
    if (!hdpa->ptrs) {   <--- bam!

So hdpa seems to be a wild pointer.

I'm uploading a log with WINEDEBUG=+dpa
For some reason I get a more interesting stack traceback than you did.
Perhaps it would help to run this under Valgrind.
