Thanks!

A sidenote on the matter: I used to have the following environment set up:
GST_GL_WINDOW=x11
GST_GL_API=egl
GST_GL_PLATFORM=gles

That was due to some forum that suggested having that combination of
environment variable. This caused my program to crush in random situations;
sometimes my program ran fine for several minutes, but sometimes it crashed
after a couple of tens of seconds. Also sometimes when changing to another
camera source the program complained about EGL_BAD_ALLOC. 

Well, now I tried the following combination:
GST_GL_WINDOW=x11
GST_GL_API=glx
GST_GL_PLATFORM=opengl

with addition of XInitThreads(). This fixed my problem. More precisely some of
it. My program doesn't crash anymore, but the memory still slowly accumulates
and I keep getting these messages in the debug log:

I believe the number after rtspsrc388 refers to the index of the connection. So
there are a lot of connections, most probably because the elements are poorly
linked, therefore not released.
