I updated to vte3-0.32.0-1.fc17.i686 and immediately started getting *** VTE ***: Failed to load terminal capabilities from '/etc/termcap' when opening a new tab in gnome-terminal-3.3.0-1.fc17.i686, and for example arrow keys didn't work. Downgrading to vte3-0.31.0-4.fc17.i686 fixed it.
Hmm. It seems like this only is seen when an existing gnome-terminal started with the old vte3 is running. After exiting gnome-terminal and starting it again it seems to work fine. The impact might thus be very low - it is just a slightly odd upgrade experience. Recommending a reboot after the update might work as a solution. Please close if you don't care ;-)
Hi Mads, I think the behaviour where opening new tabs doesn't work until gnome-terminal restart is perfectly fine for updates in a development version of Fedora. Thanks for the report!
