Description watermarkcode 2022-08-23 02:36:16 UTC

STEPS TO REPRODUCE
1.   Open dolphin on a usb device with a vfat filesystem.  
 --- Sansa clip in my case.
 --- /dev/sdb on /media/mark/0123-4567 type vfat (rw,nosuid,nodev,relatime,uid=7180,gid=9030,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)

2.   Drag a URL from another app.  (tried with both  kaggregator and QuiteRSS)  
   such as: https://dts.podtrac.com/redirect.mp3/chrt.fm/track/35917C/d2h6a3ly6ooodw.cloudfront.net/reasontv_audio_8200596.mp3





OBSERVED RESULT

Dolphin refuses immediately (without any download time)  to copy with the following error message:
"Cannot transfer file:///media/mark/0123-4567/PODCASTS/default.mp3 because it is too large. The destination filesystem only supports files up to 4GiB"


EXPECTED RESULT
I would expect that Dolphin begins downloading the file and continues downloading it until it runs out of space on the device.

NOTE: There is space on the device. I can manually copy the url using wget to the filesystem.
NOTE:  This bug just surfaced as I upgraded from Ubuntu18.04 to Ubuntu20.04.
