portmanager -slid core dumps

[Danny MacMillan]

Hi,

I am experiencing further difficulties with portmanager -slid.  I was
successfully able to delete several leaf ports.  However, when I try to
delete devel/p5-Locale-gettext or devel/gmake, portmanager core dumps
with the following message:

...
<n> Nuking gmake-3.80_2

MGdbGoTop error: invalid object type, has this object been initialised
with MGdbCreate or MGdbOpen yet?
MGdbSeek error: invalid object type
Assertion failed: (0), function MGdbSeek, file MGdbSeek.c, line 36.
zsh: abort (core dumped)  sudo portmanager -slid

Are there any practices I should be following in order to ensure
consistency of my ports tree?  In particular, are there any deleterious
consequences of using "make deinstall" to remove a port that has been
updated since it was installed?
