[mythtv-users] remote crashes mythfrontend

[James R. Van Zandt]

Mythtv used to work with our Streamzap remote, but stopped several
weeks ago.  

The remote itself is working.  The light on the receiver blinks, and
irw reports the keypresses.  For example, if I press "left" then "OK"
then "right", irw reports

    myth at eowyn:~$ irw
    00000000000028d1 00 LEFT Streamzap_PC_Remote
    00000000000028d2 00 OK Streamzap_PC_Remote
    00000000000028d2 01 OK Streamzap_PC_Remote
    00000000000028d3 00 RIGHT Streamzap_PC_Remote
    00000000000028d3 01 RIGHT Streamzap_PC_Remote

My problem is that pressing any button on the remote crashes
mythfrontend :-)

For example, after starting mythfrontend,
/var/log/mythtv/mythfrontend.log ends like this:

    ...
    2010-10-12 20:32:57.210 MythFontProperties, Error: Failed to load 'Trebuchet MS', got 'DejaVu Sans' instead

Pressing the "OK" button crashes mythfrontend, and this gets added to the log:

The frontend runs under user "myth":

    myth at eowyn:~$ ps -ef|grep front

Here's the content of /home/myth/.lircrc:

    #Custom lircrc generated via mythbuntu-lirc-generator
    #All application specific lircrc files are within ~/.lirc

    include ~/.lirc/elisa 
  
Each of those files does exist and is readable:

I'm running mythbuntu, with version 0.23.0+fixes24 of mythtv, and this version of the kernel:

    myth at eowyn:~$ uname -a
    Linux eowyn 2.6.32-25-generic #44-Ubuntu SMP Fri Sep 17 20:26:08 UTC 2010 i686 GNU/Linux

These modules are loaded:

    myth at eowyn:~$ lsmod|grep lirc
    lirc_serial             9763  0 
    lirc_i2c                5813  0 
    lirc_streamzap          7981  1 
    lirc_dev                8890  5 lirc_serial,lirc_i2c,lirc_streamzap

They're from the Ubuntu kernel package:

    myth at eowyn:~$ dpkg --search /lib/modules/2.6.32-25-generic/kernel/ubuntu/lirc/lirc_streamzap/lirc_streamzap.ko
    linux-image-2.6.32-25-generic: /lib/modules/2.6.32-25-generic/kernel/ubuntu/lirc/lirc_streamzap/lirc_streamzap.ko
    myth at eowyn:~$ debsums -s linux-image-2.6.32-25-generic
    myth at eowyn:~$

Things I've tried:

 - adding execute permissions to ~/.lircrc
 - changing the references to absolute paths, e.g.
       include /usr/home/myth/.lirc/mythtv


Any suggestions?
