Ctrl-V is broken when using >1 tabs in a file manage window. Copying (also when using Crtl-C) and Pasting itself is working correctly, no matter how many windows or tabs are open. When trying to paste inside a tab Ctrl-V fails. Pasting using the menu works. This is 100% reproducible. I am using Arch Linux and installed Thunar using the thunar-devel package [1] which installs the latest development release of Thunar. [1] https://aur.archlinux.org/packages/thunar-devel/
Works fine here.
