Bug#987449: [rc-1 graphical d-i] graphical installer hangs at language chooser step for several languages
Hello,

I spent a few hours today on this issue, but did not get very far.
Not totally unexpected if you know nothing about the installer.
I have, however, a perf top output to share. I believe this more or less means
the font rendering (pango, fontconfig) is stuck somehow?
Good luck,
Chris
