[OpenSIPS-Devel] Problem found while testing dialog profile

Hello Julien,

This bug seems to have fallen through the cracks while we were preparing 
for the release, so sorry for this.
Next time, for bug reporting, could you please use the SF tracker ?

About the actual bug, not sure if I entirely get your last message's 
point, and how would incrementing by 0 help solve the issue ?
As far as I understand, the issue appears when you get more than 10 
dialogs ongoing and you try to get the profile size ?

I will try to replicate this locally, but I'd appreciate a little bit 
more details about the issue.

Best Regards,
