Comment (by mdean):

 This is due to the line:

     fstream fin(pszFile.toAscii(), ios::in);

 which is used by the (old) Settings class to read the mysql.txt and
 settings.txt files in Settings::ReadSettings().

 There is no need to have multiple MythTV configuration files with
 overlapping functionality. I plan to remove mysql.txt and leave only
 config.xml (where config.xml allows specifying everything in mysql.txt and
 more), and ideally when doing so will remove all of the old Settings
 class.  This will leave us with only one configuration file, config.xml,
 and in so doing will remove the (extremely) old, ASCII-only, non-Qt, low-
 level C++ code that's causing the failure you've noticed.

 However, since config.xml provides the same information as mysql.txt,
 there is no need for mysql.txt if you have a config.xml file (and provide
 a <SecurityPin> value that matches your "Security PIN (required)" setting,
 as specified in mythtv-setup).  Therefore, your system can work with just
 config.xml (I use only config.xml on my 0.24-fixes system).  If you need
 help getting it to work, please ask for help on the mythtv-users list.

 Note that on 0.24-fixes and below, if you have no mysql.txt and you have
 multiple independent MythTV systems (using different databases and
 different master backends) on the same network--with multiple master
 backends running at the same time--a bug will prevent MythTV from finding
 the proper master backend automatically, so you would have to select the
 proper backend on each mythfrontend restart.  This has since been fixed in
 unstable/development code (will be a part of 0.25).

 Note, also, that for some reason, the Qt code creates a
 .config/Trolltech.conf file in both the ASCII-/latin-1-ized version of the
 HOME directory and in the UTF-8 version of the HOME directory; however,
 the one in the proper HOME directory is lacking the SQL driver and image
 format/image handler information (having only the text CODEC information--
 seemingly as if it uses the ASCII-ized version of the HOME directory name
 until it loads the text CODECs, which allow it to use the proper directory
 name).  Therefore, you may still need to have an ASCII-ized version of
 your HOME directory specifically for .config/Trolltech.conf.  This,
 however, is an upstream bug (as we don't use Trolltech.conf directly--it's
 only used in so far as it supports the Qt code that we use).
