[QGIS-Developer] Paste geometry functionality

Hi, Tomas.

I just tested the "Geometry Paster" plugin and also ran into this
clipboard size limit.  It looks like the code for the plugin tries to
avoid this problem:

csv.field_size_limit(sys.maxsize)

But this doesn't seem to have the intended effect.  On my machine,
sys.maxsize is 9223372036854775807, which appears to be too large for
setting the csv.field_size_limit.  One workaround would be to open the
QGIS Python console and set it manually to the maximum longint value:

csv.field_size_limit(2147483647)

It looks like there is already a pull request to fix this in the
plugin, from just 3 days ago:
https://github.com/nextgis/qgis_geometry_paster/pull/12/files

Cheers,
Keith
