One more odd thing... It does not fail and start looping if I launch it manually from the terminal in that sequence rather than launch it from a shell script. Triggering it could be a timing issue too...
Hmm, even if I tried your step on my test machine, I couldn't reproduce this problem... so what version of Canna are you using? I saw similar bug on ia64 and not sure if it's the real fix, but Canna works again by that fix.
I see pretty much this behaviour every time after a clean ja install of FC1 Test1/recent trees when running a GNOME session.
I never see this failure on my machine either. FC2 test1 or all earlier. Works very comfortable here, and no warning. > Warning: Select failed; error code 9 Network issue? My setting is firewall off in the office.
Yesterday I translated gnumeric ja.po for several hours on my FC2 test1, gnome-terminal, vi and kinput2. And it didn't reproduce...
I need to add to say this prob. is reported so many times on Fedora JP list too, but just doesn't happen for me...
Ok, I can reproduce this problem now. and hopefully this problem would be fixed in the next release.
This problem shouldn't appears on 3.7p1-4. please test it.
Thanks, I haven't seen any more hanging of kinput2 recently. :-)
