Vrtualdub2 crashes while executing a script with RunNullVideoPass()

Hi everybody. I have been working for years with both VirtualDub 1.10.5 prerelease and Avisynth 2.6.0, writing scripts for both so they run together. Last Saturday I decided to modify my scripts to use them with Virtualdub2 and Avisynth+. I was able to make all my scripts run, except for three pairs of them which make VirtualDub2 crash. All three VirtualDub2 scripts (in Sylia language) were using the instruction "RunNullVideoPass()", as the 3 AviSynth scripts they were running do not produce usable output. This was working fine previously with VirtualDub and AviSynth. Replacing "RunNullVideoPass()" by a "SaveAVI()" instruction makes the issue disappear. I have kept this as a workaround which allows me to carry on my work with Virtualdub2 and Avisynth+.
In order to better reproduce this issue, I have shrunk my pairs of scripts to the following ones :

Job.jobs :
VirtualDub.Open("Script.avs","",0);
VirtualDub.video.SetMode(0);
// VirtualDub.RunNullVideoPass();
VirtualDub.SaveAVI("Dummy.avi");
VirtualDub.Close();

Script.avs :
BlankClip(pixel_type="YV12").SubTitle(VersionString())

Can somebody tell me whether I made a mistake in my scripts, or I found a bug ?
