[Eric] eric4 segfaults at loading project

[Christof Hanke]

Terve,

it's me again,
even the newest versions of everything I could get segfaulted in sip
reproducibly.  This helped me finding a "workaround" :
by applying the patch below, it doesn't crash anymore.
But searching the web for "0xdbdbdbdb" and python suggests,
the maybe some refcounters are wrong ?
I might try later this week to get the crashing project-file as small as
possible, if that's of any help. Full blown tracebacks are also available.

HTH,

Christof
