Sequence cannot be opened if has no permission to write into temp dir

Currently UGENE has the dir /var/folders/qy/vzhwt50s7ns2_y33m5vjlyhh0000gn/T set up as a temp dir, in which it creates its own ugene_tmp dir.
Occasionally ugene_tmp has become owned by root with permissions drwxr-xr-x (probably because teamcity agent on my machine is launched by root user).

When I try to open assembly associated with reference, it opens assembly but fails to load sequence, honestly saying "Task

finished with error: Directory can't be created: /var/folders/qy/vzhwt50s7ns2_y33m5vjlyhh0000gn/T/ugene_tmp/p93333"
But when I try to open any sequence directly, I get an error message "Task

finished with error: No sequence objects found" which is completely not related to the case.

1. The message should be fixed
2. If temp dir becomes inaccessible, UGENE should not stop working. It should either automatically create another subdir (ugene_tmp2 or smth like that in the same parent dir) or ask user to select it.
