You're using PGTK on X.  That is unsupported and will lead to problems.

Such as the above.  The PGTK port is only intended to support platforms
other than X, and does not implement very convoluted features, such as
INCR selection transfer, that are only needed with the GDK X11 backend.

Without INCR selection transfer, large X selection transfers will lead
to Alloc errors being generated by the X server as it rejects attempts
by Emacs to store large amounts of data in window properties.

Running the PGTK port on X also leads to various other problems with
keyboard input, frame focus, and child frames.

You should build with the regular X11 support (without PGTK) instead.
