 This is because PDFedit does considerable amount of computations. Root cause of this is slowness and bad internal design of QSA (memory management issue of passed QObjects). This will be ultimately fixed by moving to QT 4.3 (this includes faster Qtscript, which also fix that design fault).

However, this is not easy, as porting from qt3 to qt4 is not trivial and qt4.2 is now stable. Qt4.3 with required features is still beta.

Another option is to move some computations from the script to helper functions, which may speed up the application too.

 This is the actual error that is thrown when the text is added.

1:KERNEL:cstream.cc:_makeXpdfObject:258: Length attribute of a stream is not valid. Changing it to buffer size.
