Bug#926634: Delays opening dialogs, possibly related to defunct fc-list process

[martin f krafft]

Package: gscan2pdf
Version: 2.5.1-1
Severity: normal




At the same time, in the debug log, I see:

 INFO - fc-list : family style file
 INFO - Spawned PID 7825

and then am left with

 madduck   7825  1.2  0.0      0     0 ?        Z    11:28   0:00 [fc-list] 
<defunct>

in the process table.



The corresponding setting is

  "pdf font" : "/usr/share/fonts/truetype/aenigma/aescrawl.ttf",

and I have to change that in the file to

  "pdf font" : 
"/usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf",

to configure a more sensible font.

When I open a session, then select a few pages and hit "save", the dialog takes about 8 seconds to show up. Given that fc-list is a fontconfig tool, I find it relevant that the "Font for non-ASCII text" in the save dialog box only contains one font, and specifically one with Unicode characters in its name, which aren't properly rendered (see screenshot attached). But the dialog still takes 8 seconds to show up, and the defunct process is still being left behind.
