Your point is no problem.  For example:

	gotom@moog:~> mkdir -p ~/lib
	gotom@moog:~> cd lib
	gotom@moog:~/lib> sudo mv /usr/lib/libbz2.so.1.0.2 .
	gotom@moog:~/lib> objdump -p libbz2.so.1.0.2 | grep SONAME
	  SONAME      libbz2.so.1.0
	gotom@moog:~/lib> mv libbz2.so.1.0.2 libbz2.so.1.0
	gotom@moog:~/lib> sudo ldconfig -v |& grep libbz
	        libbz2.so.1.0 -> libbz2.so.1.0
	gotom@moog:~/lib> grep /home/gotom/lib /etc/ld.so.conf
	/home/gotom/lib
	gotom@moog:~/lib> ldd /usr/bin/bzip2|grep bz2
		libbz2.so.1.0 => /home/gotom/lib/libbz2.so.1.0 (0x40031000)


Check SONAME of libborqt-6.9.0-qt2.3.so.

I don't know why your movement makes the program start fine.

I think this bug is not glibc, but your application side issue.
If you have no objection, I'll close this bug.
