[ubuntu-mono] [Bug 1665829] Re: MonoDevelop.exe assert failure: *** Error in `monodevelop': free(): invalid pointer: 0x000055bf61a2e6b0 ***

[Daniel Mulholland]

I think the same bug for me in Ubuntu 17.04. When I go to File > Open
before I have even selected a file I get

** Error in `monodevelop': free(): invalid pointer: 0x00007fb3c0011840 ***
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(+0x7908b)[0x7fb4157e408b]
/lib/x86_64-linux-gnu/libc.so.6(+0x826fa)[0x7fb4157ed6fa]
/lib/x86_64-linux-gnu/libc.so.6(cfree+0x4c)[0x7fb4157f112c]
[0x409ae260]

with a memory map following this backtrace which I have not included.
