Internal links failure in pdf

[gmolledaj]

Internal links not working: If I insert a link to slide 24, if I export to pdf directly the link works, the link is: file:///.../filename.pdf#%5B%7B%22num%22%3A127%2C%22gen%22%3A0%7D%2C%7B%22name%22%3A%22FitR%22%7D%2C0%2C-0.001%2C793.701%2C595.275%5D

But if I use expandanimations the link points to: #Slide%2024 and open the file browser.

Workaround: If I recover the expanded file from /tmp, in .odp format, and after opening it with impress I export it to pdf then the links work fine.
