This concerns an error in Bamboo-Invoice. When I wanted to print a pdf, I got the following error in Apache:
[notice] child pid 16395 exit signal Segmentation fault (11)
(16395 could be any number)
The cause of any “Segmentation fault” is probably PHP related. It could be because of a bad php-code compilation, or because of PHP code-error that couldn’t be caught like it would normally.
The reason here was obviously a bug in Bamboo-invoice. You can define your own corporate logo in /img/logo/logo.jpg but since I don’t have a logo at the moment I removed the file (as written in the manual). This caused the error.
Putting the image back (or any other image) resolved the error.
