Bug#405409: xbase-clients: [xconsole] Segmentation falut when the initial scroll

Package: xbase-clients
Version: 1:7.1.ds-3
Severity: normal

A xconsole process receives a SIGSEGV signal, when the xconsole
scroll the logs for the first time after its startup. For example,
when the default height of xconsole is 4 text lines, the following
script induces a segmentation fault:

/usr/bin/xconsole &
for i in 0 1 2 3; do
    echo $i
    logger "test.sh: $i"
    sleep 1
# END of test script

There seems to be a workaround: After a xconsole process starts,
focus the xconsole and push Ctrl-C (i.e., clean up logs in
the xconsole). Then, scrolls don't induce any segmentation fault
in my Debian box.
