Comment 68 for bug 531719

I'm confused: I downloaded the Linux/x86_64 version of Seamonkey 2.0.7 from the project's page. (Build identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.12) Gecko/20100825 SeaMonkey/2.0.7)

I ran ldd on Fedora's seamonkey-bin and on Mozilla's seamonkey-bin; they link exactly to the same dynamic libraries (only the addresses changes).

For example, the three relevant (I think) libraries:

Fedora:
libpangocairo-1.0.so.0 => /usr/lib64/libpangocairo-1.0.so.0 (0x00007f46a58b0000)
libpango-1.0.so.0 => /usr/lib64/libpango-1.0.so.0 (0x00007f46a5665000)
libcairo.so.2 => /usr/lib64/libcairo.so.2 (0x00007f46a53ec000)

Mozilla:
libpangocairo-1.0.so.0 => /usr/lib64/libpangocairo-1.0.so.0 (0x00007f91d1364000)
libpango-1.0.so.0 => /usr/lib64/libpango-1.0.so.0 (0x00007f91d1119000)
libcairo.so.2 => /usr/lib64/libcairo.so.2 (0x00007f91d0ea0000)

/usr/lib64/libcairo.so.2 is system cairo, right?

Both versions seem to link the same cairo library, yet Fedora's version crashes, while Mozilla's version does not. How would one explain this?
