            Bug ID: 514721
           Summary: Digikam tends to crash with no error message on the
                    first attempt at a duplication search on a folder with
                    a larger number of images, but not on post-restart
                    attempts
    Classification: Applications
           Product: digikam
      Version First 9.0.0
       Reported In:
          Platform: Microsoft Windows

            Status: REPORTED
          Severity: normal

SUMMARY
On a clean/fresh boot, for probably 20 beta releases, I have seen this behavior
where if I select an album that has some number of images- perhaps 100, perhaps
1000- dont know the trigger if any- a right-click 'find duplicates' command
seems to pause for several seconds, and then Digikam crashes (closes with no
error message). Strangely, if I restart Digikam without a machine logout or
restart (Windows), it doesnt seem to crash for the exact same process. I have
no explanation, just the hypothesis that some process remains running
post-crash that cases the next instance of that process to behave differently.
Memory overrun or who knows-


STEPS TO REPRODUCE
1.  As outlined, pick a nested folder with some number of files in it- where
those images have already been fingerprinted etc
2. Right click on the album, select find duplicates


OBSERVED RESULT
Seems that on a clean machine/Digikam start, there is a sort of 50/50 chance
for a crash. I dont know if this is related to the number of files in the
album, or the length of paths etc. But, on restart of Digikam right after
crash, a repeat of the same find duplicates command on the same folder doesnt
seem to crash- at least I havent seen that happen early in the search process.
So, its not something inherent with the folder name or a file count etc

EXPECTED RESULT
Proper search and output of any matches
