libopenhbci2 incompatible with Finance::Quote

[David Hampton]

I've tripped across a problem trying to run a hbci enabled version of
gnucash.  This problem recently appeared when I updated from using
openhbci to openhbci2.  The error occurs when gnucash runs
finance-quote-check and then waits for the process to finish.  I
consistently get the following errors at this point:

=====

5:2004/03/04 15-11-52:(null):process.c:  129: No information about
process "17568" available

=====

Gnucash then summarily quits.  Thanks to a suggestion from Derek, I
tracked the problem back to the GWEN_Process_ModuleInit() function in
gwenhywfar-0.9.6 (a prerequisite of openhbci2).  This function installs
a signal handler to catch the SIGCHLD signal, apparently overriding the
guile signal handler.  Guile doesn't accept this situation, thus the
problem.  If one of the hbci developers on the list would work with the
gwenhywfar developers to resolve this problem, I would appreciate it.
