dillo mysteriously freezes

by dennisn＠dennisn.dyndns.org

I seem to be experiencing a very nasty bug that breaks my Dillo. A few seconds after starting dillo, it "freezes" -- standard-output stops, the graphics freeze and never get redrawn (resulting in those psychodelic effects of moving windows over a non-redrawing window). My dillo window then doesn't respond to my window manager's "close" events, and I have to manually kill it. I can't give you the exact steps to reproduce it -- sometimes it's like this immediately after starting ... sometimes it magically starts to happen a few seconds afterwards -- possibly after I click on a link. dillo-2.2 fltk-2_pre7513 (I also tried with earlier versions (6970)) Ideas?

Sounds like the package > manager script is missing a depend check. My guess is that "fixed" and "variable" may be standard enough that it's a misconfiguration not to have the aliases present and set to a font that you have, although, yeah, it's a bug in fltk2 not to handle that gracefully. > As far as having the extra eye-candy, I prefer only building/installing stuff > that's needed versus installing a mess of eye candy I don't make much use of. > Hence, the reason why I skipped building "without xft". ;-) Well, it "should" :) 1) not crash 2) print a warning to the terminal if dillo can't use the fonts that it's set to use. In any case, I should update the comments in the fonts section of dillorc to reflect the current state of things. Most/all of the text in that section hasn't been touched since the dillo1 days.

I believe I keep things minimal, and rely primarily on bitstream fonts -- with the occassional Terminus and Dejavue (as supposedly Dillo like Dejavue fonts). Dillo is set to use DejaVu fonts by default (set in dillorc file), but your backtrace showed that fltk is using Font_xlfd.cxx instead of Font_xft.cxx, indicating that your fltk was configured with --disable-xft. With xft disabled, it's not going to use TTF fonts. If you don't mind using antialiased fonts, you could reconfigure with xft enabled, and recompile, and everything may just magically work. If not, and you like bitstream, I'd alias 'fixed' to one of the bitstream terminal choices, and alias 'variable' perhaps to one of the bitstream charter ones. (And then I think you'd have to run mkfontdir afterward.)
