Update font preview in Text and Font dialog broken (trunk, Ubuntu 13.10)

[Vladimir Savic]

Inkscape trunk (stable works, tested with what Ubuntu 13.10 provides in default repository) has broken font preview in dedicated dialog - Text and Fonts. No matter what font is set to be default, preview area is always empty.

If you even manage to force dialog to show glyphs (from time to time they appear) it's always stay pinned to placeholder text. As if font choice has no effect on preview area. Apply button works and canvas gets updated though.

$inkscape -V
Inkscape 0.48+devel r12700 custom (Oct 16 2013)
Ubuntu 13.10

Image attached for demonstration. Single instance of Inkscape is running.

Not reproduced on Windows XP, Inkscape trunk revision 12701.

Not reproduced with r12676 on Ubuntu 13.10, going to pull down latest changes and recompile though.

Not reproduced with r12715 either, text updates as expected.

It was a problem with units. Su_v figured it out. If document had default units set up to be anything but default and font size was not integer value, display was messed up. Now you can text again and confirm it to be fixed. Seems OK to me now.

Closing based on the reporter's feedback ("Seems OK to me now.").

Feel free to reopen if the error re-occurs with 0.91.x or current trunk (please provide details 'steps to reproduce' if possible).
