Scanning huge folder results in weird behaviour

[schimschewski]

i'm using very often the "open folder"-feature to export the entire movies in subdirectories e.g.
this was working like a charm in <= version 23.x

since 24.0.1 there seems to be a limitation or some cache problems, it does not show up all results. reopening the folder results in getting some missing files (sometimes only 5 and 10) from the first attempt.

i'm not able to find out, what exactly triggers this behaviour.
Rescanning the folder after closing the application results sometimes in other results.
Rescanning the folder without closing shows very strange behaviour, as seen in the screenshots.

splitting the huge folder into 2-3 folder is fine. but i have to close the application after each scan.
its not a certain file.
its not an issue in 64bit-cli.
its an issue in 32bit-cli.
