mysql - phpMyAdmin 4.0.5 export error bug - anyone know if it is being addressed? -

phpmyadmin has announced in few days on sept 1st 2013 they're closing down other resources such mailing list , forums , deferring use stackoverflow / stackexchange.

i provide general support @ small cpanel hosting service , part of duties include doing frequent db exports in phpmyadmin , showing hosting customers how export databases phpmyadmin within cpanel backup tool.

been working fine many years , across many servers / cpanel versions / php versions / mysql versions.

but after upgraded phpmyadmin 4.0.5 final (we use whm's easyapache keep php , other server modules updated regularly) we're encountering apparent bug , cannot export databases.

any attempt export db on size (haven't determined yet, seems around 20mb) instead of getting usual download prompt, fails.

if export attempted in firefox error looks this:

firefox can't find file @ https://example.example.net:2083/cpsess1210889896/3rdparty/phpmyadmin/export.php 

if export attempted in internet explorer says "the website cannot display page" , when more info clicked says:

this error (http 500 internal server error) means website visiting had server problem prevented webpage displaying.  

since upgrading 4.0.5 started happening db's i've been exporting through phpmyadmin years, literally, no problem before.

i tried raising memory limits within whm / cpanel such max memory cpanel session can use, doesn't help. couple of discussions on cpanel forums seem claiming problem stems bug in phpmyadmin, not problem cpanel or php.

can shed more light on problem?

is there phpmyadmin knows if specific issue being addressed?

thanks or feedback here willing provide. putting me in bit of jam our clients.

just in case matters here general server environment:

cpanel/whm 11.38.2 (build 6) apache 2.2.25 php 5.4.18 mysql 5.5.32-cll rhel 5 64bit running suphp 

edit - forgot mention problem occurs whether doing straight "quick" sql export and/or "custom" compressed export (such gzip). either way, quick or compressed can't export databases larger around 20mb.

update / fix - marc delisle's code changes in phpmyadmin 4.0.6 fixes bug, , after cpanel 11.38.2.7 "release" came out has resolved issues on servers. thank marc , pma team!
