Description

QGIS tells me

Warning 4: Failed to open /opt/qgis-git/share/qgis/resources/data/world_map.shp, Permission denied.

The file exists and is world readable

-rw-r--r-- 1 root root 528032 Jan 23 23:06 /opt/qgis-git/share/qgis/resources/data/world_map.shp

strace suggests that QGIS is trying to access the file with write access.

openat(AT_FDCWD, "/opt/qgis-git/share/qgis/resources/data/world_map.shp", O_RDONLY) = 76
openat(AT_FDCWD, "/opt/qgis-git/share/qgis/resources/data/world_map.shp", O_RDWR) = -1 EACCES (Permission denied)
stat("/opt/qgis-git/share/qgis/resources/data/world_map.shp", {st_mode=S_IFREG|0644, st_size=528032, ...}) = 0
stat("/opt/qgis-git/share/qgis/resources/data/world_map.shp", {st_mode=S_IFREG|0644, st_size=528032, ...}) = 0
openat(AT_FDCWD, "/opt/qgis-git/share/qgis/resources/data/world_map.shp", O_RDONLY) = 76
stat("/opt/qgis-git/share/qgis/resources/data/world_map.shp", {st_mode=S_IFREG|0644, st_size=528032, ...}) = 0
openat(AT_FDCWD, "/opt/qgis-git/share/qgis/resources/data/world_map.shp", O_RDWR) = -1 EACCES (Permission denied)

As the file is used as source for the CRS display it does only require read access.

Opening it in read-only mode should get rid of the warning and be what was intended. :)

This is harmless - OGR tries to open r/w and falls back to r/o after that. But this is just for the map display in the CRS selection dialog.
