dbus/GT4 problem after an update, then reboot

[Gene Heskett]

Greetings all;

A script that I have been using for 3 or 4 years seems as if it is now 
broken.  This script sends inotifywait off the watch the incoming mail 
spool directory, and when a file has been closed, and inotifywait returns 
the filename, then sends kmail a message over the dbus circuit to go get 
the mail.

That command line that has tickled kmail from my now elderly script:

/usr/bin/qdbus org.kde.kmail /KMail org.kde.kmail.kmail.checkMail

is now eliciting this error on the screen it was launched from:

/usr/bin/qdbus: symbol lookup error: /usr/lib/libQtDBus.so.4: undefined 
symbol: _ZN14QObjectPrivate15checkWindowRoleEv

So now I have to click on checkmail from time to time as my incoming mail 
is no longer automatic.

Can anyone help, or is this a newly hatched bug in libgt4-dbus?  Searching 
in /var/cache/apt/archives shows that file has not been recently updated, 
only:

Thanks for any clues here.

Cheers, Gene
