Program crashes while trying to do a check in constructor

[hakermania]

Hi, I have 2 .ui files. One is the main and the other is the preferences window(this is actually a QDialog). In the constructor of the preferences window i have added this code to check if the second line of a file contains the char "1". Unfortunately then the program craches (this is the reason for sure, because when I comment this piece of source then it works fine...
This is the source:

char homee[150]="/home/";
	strcat(homee,py); //py is the current logged on user 
        char otherr[100]="/.config/on_launch_enabled_options";
	strcat(homee,otherr);
	char line [ 128 ];
	int i;
	FILE *file = fopen ( homee, "r" );
   	for ( i = 0; i < 1; ++i )
   	{
       	fgets ( line, sizeof line, file ); }
   	fclose ( file );
   	if(!strcmp (line,"1\n"))
       	ui->checkminimizeonlaunch->setCheckState(Qt::Checked); else ui->checkminimizeonlaunch->setCheckState(Qt::Unchecked);

char homee[150]="/home/";
	strcat(homee,py); //py is the current logged on user 
        char otherr[100]="/.config/on_launch_enabled_options";
	strcat(homee,otherr);
	char line [ 128 ];
	int i;
	FILE *file = fopen ( homee, "r" );
   	for ( i = 0; i < 1; ++i )
   	{
       	fgets ( line, sizeof line, file ); }
   	fclose ( file );
   	if(!strcmp (line,"1\n"))
       	ui->checkminimizeonlaunch->setCheckState(Qt::Checked); else ui->checkminimizeonlaunch->setCheckState(Qt::Unchecked);

Thx for any replies.
Notice that if I do the same thing in a Qt-console application it works fine
(changing ui->checkminimizeonlaunch->setCheckState(Qt::Checked); else ui->checkminimizeonlaunch->setCheckState(Qt::Unchecked); to cout << "Strings Are similar\n"; )

It crushes exactly at the point it says fgets ( line, sizeof line, file );
