Beagle-extract-content runtime error

[Andrew Leung <aleung soe ucsc edu>]

Hi,

I'm running the beagle-extract-content program from within my C++  
program using popen() to get a pipe to the programs output. I am then  
reading file keywords into my program from beagle-extract-content. The  
program is parallelized to crawl several directories with each thread  
instantiating a separate beagle-extract-content instance.

I frequently get runtime errors from beagle-extract-content. I have  
attached the stacktrace that it spits out to the bottom of the email.  
I have beagle running on Ubuntu 8.04 with Mono JIT compiler version  
1.2.6. Any ideas what is going on with this? Thanks.

Andrew
