Seafile client 6.1.5 download a file fails

I have really tons of data on my Seafile server. Now on a Windows machine with client 6.1.5 installed, I wanted to download a file from a library, which library is not synced on that machine. The file is 7.9GB in size. Seafile client crashes after reaching a huge physical memory allocation.
I think this may be a bug in the client?

Is it a problem to download the file via browser?

No, in fact the solution was to download via browser, as I needed that file urgently.
I just used to use the clients cloud browser, because it’s handy, and I didn’t have a problem so far.
I suspect it’s a Windows related bug, because on Linux I can download the very same file without a problem.
