I have the same issue on Debian with PCManFM. A bit of searching 
turns up this bug report for the `shared-mime-info` database, 
which seems to be the root of the problem:

[Since Debian 9][1], pretty much all Debian-based distros have 
their C toolchain set up to produce position-independent 
executables by default. So you will probably need to have DMD 
pass `-no-pie` when it invokes GCC to link the executable (or do 
a separate link step and pass it yourself).
