Description Charles R. Anderson 2007-09-24 23:07:00 UTC 
Description of problem:

Running wireshark on a minimal system results in this error message:

No fonts found; this probably means that the fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about fontconfig can be found in the fontconfig(3) manual

Version-Release number of selected component (if applicable):
0.99.6-1.fc6

How reproducible:
always

Steps to Reproduce:
1. install minimal system without X
2. yum install xauth wireshark-gnome
3. ssh -X remotehost and run "wireshark"
  
Actual results:

# wireshark
No fonts found; this probably means that the fontconfig
library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information
about fontconfig can be found in the fontconfig(3) manual

# wireshark

... runs correctly ...

Expected results:
wireshark-gnome should have proper Requires: for whatever fonts it needs to run,
so they get pulled in automatically with "yum install wireshark-gnome".

Additional info:

I'm not sure of the exact Requires here, I ran the following commands in this
order until wireshark started working:

yum install wireshark-gnome
yum install xauth
yum install xorg-x11-font-utils
yum install xorg-x11-fonts-misc
yum install xorg-x11-fonts-base
yum install xorg-x11-fonts-truetype
yum install xorg-x11-fonts-Type1

lsof shows the running wireshark-gnome has these font files open:

wireshark  8492      root  mem       REG      253,0    77488   24249271
/usr/share/X11/fonts/Type1/l047013t.pfa
wireshark  8492      root  mem       REG      253,0    70121   24249279
/usr/share/X11/fonts/Type1/l048013t.pfa
wireshark  8492      root  mem       REG      253,0    72496   24249281

Comment 1 Bill Nottingham 2007-10-03 16:54:01 UTC 
The problem is twofold:

1) apps that use fontconfig almost certainly need some sort of fonts

2) you can't really have requires to do this correctly, as any font that an app
requests will go through both the system font aliasing, and *any user's own font
configuration*. So there's no way to synthesize 100% correct requires back to a
package or file name.
