[Kolab-devel] /usr/lib/php5/20100525/kolabobject.so crash

[Christoph Erhardt]

Hi Vidmantas,

this is a known bug (see https://issues.kolab.org/show_bug.cgi?id=2050).
I have been digging into it lately, but have yet to come up with an
appropriate fix since the issue is really complex.

For the time being, see comments 8 and 11 in the bug report for possible
workarounds.

Best regards,
Christoph
