it should reallocate the string, which usually only happen if the string gets too big to fit into its original place. Currently I have no recent glib source to check if I’m right.<o:p></o:p></span></p>

<p class="MsoNormal">Hi Balabit et al,<br />
<br />
When using the sanitize-utf8 flag I am hitting a g_assert in modules/syslogformat/syslog-format.c; what could be causing this?<br />
<br />
Any advice welcome!!<br />
