OwnCloud client crashes windows

Please help us by providing the following info. Before posting please make sure that you're running the latest available version for your oC release: https://owncloud.org/changelog/ + https://owncloud.org/changelog/desktop/

Steps to reproduce
1. Install OwnCloud client Windows
2. Attempt to sync > 300,000 - 900,000 files
3.

Expected behaviour
Tell us what should happen
The file sync should complete normally albeit completion time dependant on number of files as well as total data size downloaded/uploaded

Actual behaviour
Tell us what happens instead
For filecounts > approximately 400,000, the sync client crashes with messages from Visual C++.
The similar version of ownCloud sync client for 64-bit Ubuntu appears to work fine for > 1 million files (about 50TB data)
However, the similar version of the ownCloud sync client for 32-bit Ubuntu has similar problems as the Windows client.
I suspect that the 32-bit clients will crash for > ~ 300,000 files

Hi,

thanks for your detailed report. Unfortunately it need to redirect you to https://github.com/owncloud/client/issues to report this issue directly to the sync client developers.

Posting such issues in here mostly getting lost and not fixed.
