 Hi all,

 well, after reading Jef's post about the "translation" of gdb backtrace, I
 made a test with a fella's computer. He has the same OpenSuse as me, but
 instead of having installed PostgreSQL from EnterpriseDB, he installed the
 packages provided by openSuse through YaST (say so, an 'standard'
 installation)... and it worked perfectliy, so I realized that the problem
 could be where Jef pointed.

 Because of my lack of deep knowledge about linux internals, I've done a
 'brute force approach' to try to solve the problem, and... It worked!!!!

 I've done the following

 1) First I've located all the libcrypto related files:


 {{{
 /opt/lampp/lib/libcrypto.so
 /opt/lampp/lib/libcrypto.so.0.9.8
 /opt/lampp/lib/pkgconfig/libcrypto.pc
 /opt/PostgreSQL/8.4/lib/libcrypto.so.4
 /opt/PostgreSQL/psqlODBC/lib/libcrypto.so.4
 /usr/lib/libcrypto.a
 /usr/lib/libcrypto.so
 /usr/lib/libcrypto.so.0.9.7
 /usr/lib/libcrypto.so.0.9.8
 /usr/lib/libcryptopp.a
 /usr/lib/pkgconfig/libcrypto.pc
 }}}

 2) Then I've moved away (to a subfolder in
 /opt/PostgreSQL/8.4/lib/libcrypto.so.4) the file libcrypto.so.4 for safety
 reasons

 3) then I've created a symlink to /usr/lib/libcrypto.so in
 /opt/PostgreSQL/8.4/lib/ with the name libcrypto.so.4

 And voilà, QGis works again.

 So I have to apologize for thinking that thas was a bug in QGis, and I
 have to appreciate all the help received from you.

 I hope that someone of you could explain what I did for future reference,
 and also, please tell if the bug could be marked as solved, I don't know
 if what I've done is enough.

 Thank you very much again

 jorge Tornero
