QGIS crashes when opening project file with nonexisting NTV2 grid file location

Affected QGIS version: 2.18.7
Redmine category:project_loading/saving

When I open a QGIS project created on Windows QGIS installation (see attachment), it crashes QGIS on Linux.

I found out that the reason for that crash is in QGIS project Coordinate system definition in *.qgs file. When there is custom coordinate system definition that uses NTV2 grid file for datum transformation, it crashes QGIS (see line 28 in qgs file from attachment. Probably because that file (D:\HRNTv2.gsb) does not exit on Linux OS.
For example, if you open a QGIS project file from the attachment, you will find something like this:

<title></title> meters 5388731.26843392010778189 5021504.89625283982604742 5389744.13858615513890982 5022828.19216307904571295 0 1 *+proj=tmerc +k=0.9999 +lon_0=15 +no_defs +x_0=5500000 +ellps=bessel +nadgrids=D:\\HRNTv2.gsb +units=m +lat_0=0 +wktext +y_0=0* 100000 0 USER:100000 5 zona tmerc bessel false

...
...
...

Problem is in the bold text. When I delete that line from .qgs file, it works without any problem. I believe that QGIS crashes because he can not find file D:\HRNTv2.gsb on my Linux machine. I have that file somewhere else on my computer.

To repoduce this error:

• unzip attachment
• open Novigrad_2008_upu_stancijeta_1.qgs file
• and crash

Thank you for your help and best regards,
Mario

I cannot reproduce with latest QGIS 2.18.14 or QGIS master on Ubuntu 16.04. If you reproduce, could you give the stacktrace when the crash occurs

Yes, you are right. The problem does not exist on 2.18.14 version. QGIS works normally.
