I installed qpdf2 on my stock sharp rom on my 5600. I also installed libopie1_1.0.3_arm.ipk and opie-pics_1.0.3_arm.ipk as per FAQ on OESF.org. When I try to open a pdf document it starts to open and then I get "the available work area is becoming low. Please select an application to terminate" and then it closes. The only thing I installed on my sharp rom is the sharp terminal and file manager, so I should have plenty of room. I also tried installing to cf but same thing. Is there something else I should be trying?
